Introduction
Over the past 50 years, restaurant businesses have experienced significant growth (Khan et al., 2023a), contributing billions of dollars to every country's global economy by employing millions of people in the restaurant network (Yadav and Dhar, 2021).International financing organizations from developing countries see investment in this sector as a viable strategy (Khan et al., 2023b).However, restaurant practitioners recognize that in a highly competitive market (Selem et al., 2023c).While some restaurant practitioners prioritize commercial outcomes over civilized behaviors of front-line employees, there is growing interest in creating an environmentally friendly work environment in the restaurant sector (Khan et al., 2023c).
Front-line restaurant employees, particularly co-workers, are being studied for various reasons.First, the restaurant service requires constant employee-customer interaction (Ugwu et al., 2022).Second, the restaurant industry is highly service-oriented, with employees' behavior changing regularly (Chen et al., 2021).Co-worker friendship is an important concept that differs from other types of friendships in that it is voluntary and comprehensive (Khan et al., 2023c).Hence, co-workers can establish workplace friendships, posing more interactive potential than those with individualized or highly supervised practices.The emergence of work-related problems, including problems with supervisors, leads to employees sourcing relevant support from their co-workers (Guo et al., 2022), contributing to closer relationships (Ugwu et al., 2022).Co-workers spend most of their time in the workplace in social discussions, where negative gossip can alter their focus (Khan et al., 2023a).
In the context of co-worker friendship, gossip is a natural social phenomenon affecting people's hearts, minds, and actions (Khan et al., 2023b).Gossip is an unavoidable social phenomenon affecting social settings.When two people communicate, incivility frequently arises (Khan et al., 2023c), whether they are co-workers, supervisors, or customers (Ugwu et al., 2022).Although empirical research on workplace incivility is expanding, the reasons behind co-worker incivility in the restaurant industry have not received much attention (Khan et al., 2023b).Despite the ubiquity of unsavory behavior in the hospitality industry, workplace characteristics capable of mitigating its influence have yet to be researched.Ugwu et al. (2022) demonstrated that half of employees are perceived as leaving their occupations because some try to avoid troublemakers.
Despite existing studies on the moderating influence of promotion on co-worker friendship-incivility relationships (Neubert et al., 2008), there is a significant gap in the literature.While previous research has highlighted the impact of a promotion-focused orientation on employee performance outcomes, particularly creativity, and willingness to assist others, it frequently overlooks the nuanced dynamics introduced by promotion focus to workplace interpersonal relationships.Our research fills this void by highlighting the potential negative impact of a promotion focus on co-worker friendships, in which individuals may prioritize personal advancement over nurturing close relationships.In addition, despite acknowledging the diversity among hotel employees (Boo et al., 2013), the research landscape lacks an in-depth investigation of how gender moderates the relationship between negative gossip and co-worker incivility.
Our paper contributes to a more thorough understanding of complex workplace dynamics by introducing gender as a critical moderating factor in the co-worker friendship-incivility dynamic, paving the way for future investigations into the combined impact of promotion focus and gender on interpersonal relationships and incivility in diverse professional environments (Yadav and Dhar, 2021).The following questions are addressed in this paper: (1) To what extent does close co-worker friendship influence negative workplace gossip?(2) What role does negative workplace gossip play in developing and increasing workplace incivility?(3) To what extent does negative workplace gossip mediate the relationship between incivility and close co-worker friendship?(4) Does the relationship between co-worker friendship and negative gossip differ depending on individual differences in promotion emphasis?(5) How does gender influence the relationship between workplace gossip and co-worker incivility?
Lastly, this paper contributes to the current knowledge on co-worker incivility influenced by negative gossip about close co-workers.First, negative gossip has rarely been discussed in other contexts.Thus, studying negative workplace gossip can predict hostile restaurant employee behavior (Ugwu et al., 2022).Second, adding promotion focus and gender as moderators is the potential contribution of the study due to the increased importance of better service under the umbrella of affective events theory (AET).Accordingly, this paper adds to AET with a limited understanding of explaining and predicting co-worker incivility.

Underpinning theories
In supporting our hypotheses, we utilized the AET introduced by Weiss and Cropanzano (1996).This theoretical framework has been previously applied in diverse contexts.While AET has been extensively employed in organizational studies to explain employee behavior, its application as a standalone theory for understanding individual behavior within the hospitality sector is relatively uncommon.AET posits that individuals' emotional states fluctuate over time, with work-related activities as immediate precursors.Moreover, it suggests that changes in a person's emotions can play a pivotal role in shaping behavioral responses (Weiss and Cropanzano, 1996).AET underscores the interplay between dispositional traits, situational factors, work-related events, and affective responses.
AET is also instrumental in examining co-worker friendship relationships and incivility in the hospitality industry (Khan et al., 2023b).According to AET, the reciprocal relationship between individuals and their circumstances significantly influences their responses to events (Weiss and Cropanzano, 1996).Previous research has demonstrated that co-worker friendship can induce lifestyle changes and foster social bonding, resulting in civil behaviors (Ugwu et al., 2022).In our study, Employees who are the subject of unfavorable rumors at work struggle with an unethical workplace culture and run into unethical behaviors from close co-workers.Figure 1 illustrates the proposed links in our model, aiming to elucidate how co-worker friendship influences negative gossip and incivility among close co-workers in a restaurant setting.
Even though emotions play a crucial role in AET, this paper aimed to investigate how interpersonal dynamics and work-related events might cascade into negative workplace behaviors (Khan et al., 2023a).Although our study does not explicitly measure emotions, we

Co-worker friendship in restaurant
believe that emotions are intrinsically linked to the notions being studied.For example, negative workplace gossip can elicit various emotional reactions, and co-worker incivility is probably affected by the emotional states of those engaged in the workplace (Selem et al., 2023c).

Co-worker friendship
Recognition of the significance of workplace relationships to organizational processes within the hospitality domain is well-established in hospitality scholarship (Ugwu et al., 2022;Yang et al., 2021).Co-worker friendship, a pertinent aspect of these relationships, emerges as workplace interactions between co-workers evolve into meaningful connections (Sias et al., 2012).Potgieter (2019) diligently explored the initiation and progression of workplace friendships, emphasizing the impact of individual and environmental factors.Khan et al. (2023c) assert that a combination of individual and environmental factors influences the development of co-worker friendships.Individual features, such as personality traits and perceived similarities, are crucial in forming these connections (Khan et al., 2023a).Individuals naturally gravitate towards others with similar interests and exhibit admirable personalities (Khan et al., 2023c).Furthermore, co-worker relationships often deepen when employees seek support from their colleagues during work-related challenges, fostering a more robust bond (Chen et al., 2021).
This paper defines co-worker friendship based on individual characteristics (e.g.personality and perceived similarities) and environmental factors (e.g.work-life events, shared activities, and socializing).Throughout different phases of relationship formation, personal and contextual factors influence workplace friendships (Khan et al., 2023a).Noteworthy elements contributing to initiating workplace relationships encompass proximity, perceived resemblance, shared tasks, personality traits, and social interactions-all relevant to this study's scope (Sias et al., 2012).

Negative workplace gossip
In the absence of a third party, workplace gossip involves official and informal co-worker conversations (Sias et al., 2012).Gossip is "evaluative" and maybe both positive and negative (Khan et al., 2023c).A social comparison technique called gossip evaluates a person's characteristics.As a result, employees are said to utilize gossip as one of the fundamental techniques for empowering informal ties in organizations.
The severity of these informal interactions may promote or discourage cooperation inside formal work teams and across the whole business (Ugwu et al., 2022).This paper focuses on negative workplace gossip since co-workers gossip negatively about each other due to the competition among them (Wu et al., 2018;Potgieter, 2019).Negative workplace gossip is more about ridiculing co-workers and disrespecting their opinions through gossip.
Otherwise, negative workplace gossip can have comparable implications to victimization, such as restricting organizational achievement and sabotaging the basic psychological urge to belong (Cheng et al., 2022).Employees who have been victimized often struggle to cognitively regulate their social surroundings by trusting other people (Brady et al., 2017).Negative workplace gossip is an informal discourse about another co-worker who is not there.
Gossip and interpersonal friendship links are fundamental to informal organizational relationships (Khan et al., 2023c).These links are vital to formal organizations since prior studies have shown that employees are more collaborative and effective when informal ties follow official contacts (Yang et al., 2021).Drawing on AET, this relationship holds significant importance since negative workplace gossip is caused by negative emotions (Weiss and Cropanzano, 1996); however, negative emotions may be reduced in the presence of a coworker's friendship.Hence, this paper proposes that: EJMBE H1.Close co-worker friendship negatively affects negative workplace gossip.

Co-worker incivility
Workplace incivility is characterized or defined as an increase in the exchange of activities between employees (Khan et al., 2023c), leading to more severe behaviors like abusive behaviors, violence, noncompliance, or antisocial behaviors (Cortina et al., 2001).While most examples of unproductive workplace behaviors focus on the perpetrators, research on workplace incivility focuses mainly on victims' negative job-related psychological and physical effects (Khan et al., 2023c).However, research on antecedents is scarce.
Low-level interpersonal mistreatment constitutes impoliteness (Selem et al., 2023a).Incivility would be at the lower end of a spectrum of psychological deviance's level or intensity if such a continuum existed (Khan et al., 2023b).Accordingly, moderate-intensity hostility, such as unpleasant remarks and condescending language against a co-worker, would be considered impolite, while higher-intensity aggression would not.Cheng et al. (2022) argue that negative workplace gossip activates co-worker disparagement and increases stress.The AET principles can help us comprehend how an individual's internal variations of work-related event experiences (i.e.negative workplace gossip) throughout a day may potentially influence their subsequent behaviors (i.e.co-workers' incivility) (Khan et al., 2023c).Hence, this paper proposes that: H2.Negative workplace gossip positively affects co-worker incivility.
To answer the question, "How does co-worker incivility behave when friendship among frontline co-workers of a restaurant increases in the presence of negative workplace gossip?"We employed AET with various justifications to allow front-line restaurant employees to partake in workplace gossip depending on their relationships and interactions.We argue that employee behaviors are shaped by social settings, particularly those based on some event.These social situations include employee interpersonal relationships based on emotions (Khan et al., 2023b).The hospitality sector is a competitive industry, and tasks are completed through interactions between people (Yang et al., 2021).Employees come from various backgrounds, resulting in friendly exchange among multiple stakeholders (Ugwu et al., 2022).
Co-worker friendships are established based on shared interests and lifestyles in these situations.This friendship in the hotel sector allows employees to engage with one another, and it is through this interaction that workplace gossip occurs (Chen et al., 2021).Yang et al. (2021) argued that co-worker friendship significantly affects hotel employee behaviors.Most workplace gossip concentrates on the effect of a particular aspect of gossip on behavioral outcomes (Khan et al., 2023c).Chen et al. (2021) proposed that negative gossip about close co-workers has severe effects, such as undermining the fundamental psychological need to belong and encouraging coworker incivility.According to Guo et al. (2022), employees subjected to gossip were less likely to have strong working connections with their co-workers and were more likely to quit their jobs.Therefore, this paper proposes that: H3.Negative workplace gossip mediates the co-worker friendship-incivility relationship.

Promotion focus and gender as moderators
Our study hypothesizes moderating effects at two links to investigate the temporal dynamics of co-worker friendship and incivility.This choice is based on the contemporary nature of workplace processes and how different moderating factors may exert influence at various stages (Chang and Teng, 2017;Yadav and Dhar, 2021).Schabram et al. (2023) emphasize the importance of considering temporal variations in moderating effects within dynamic workplace settings.

Co-worker friendship in restaurant
Self-regulation theory can explain the relationship between promotion focus and negative workplace gossip (Higgins, 1997).Promotion-seeking individuals are motivated by aspirations for advancement.A promotion-focused mindset in co-worker friendships may lead individuals to gossip to promote their goals or gain a competitive advantage (Ferris et al., 2008).According to the literature on self-regulation and workplace behaviors, promotion focus can shape interpersonal interactions, including the spread of negative workplace gossip.Schabram et al. (2023) and Yadav and Dhar (2021) argue that promotion-focused employees offer various potential solutions, whereas prevention-focused employees want to prevent destructive workplace behaviors.In sum, employees with a promotion focus evaluate the issue from different angles and develop various ideas to address it.For instance, promotion-focused co-workers may create negative emotions (e.g.selfish behaviors to get promotions) (Schabram et al., 2023), leading them to gossip negatively with others about their immediate co-workers.Hence, we assume that: H4.Promotion focus moderates the association between co-worker friendship and negative gossip.
Gender as a potential moderator of incivility stems from research on gender differences in communication styles and conflict resolution strategies (Selem et al., 2023a).Gender may influence the perception and expression of incivility in workplace interactions, according to these studies.We believe that by including gender as a moderator, we can better understand how gender dynamics shape the occurrence and consequences of incivility among restaurant employees.Recent scholars argue that gender can influence individual appraisals of emotional reactions (Boo et al., 2013;Yadav and Dhar, 2021).Men and women have distinct perspectives on work and life, which causes differences in their actions, accomplishments, and outputs (Guo et al., 2022).Men are considered analytical, risk-taking, and choosy, while women are deemed unselfish, caring, and all-inclusive (Boo et al., 2013).
Similarly, these gender variances are reflected in how people approach their work, formulate their strategies, and handle grievances (Selem et al., 2023a).Generally, it is empirically supported that women tend to be more frequently subjected to uncivil behaviors than men (Cortina, 2008); however, organizational culture can play a crucial role in shaping the uncivil behaviors between men and women (Greer and Peters, 2022).For instance, organizations that actively embrace female participation may demonstrate lower incidences of uncivil behaviors compared to male-dominated environments (Saxena et al., 2019).Hence, we assume that: H5.Gender moderates the linkage between negative gossip and co-worker incivility.

Research context
Egypt is distinguished by its hospitality business and unique institutional environment characteristics (Selem et al., 2023c).However, prior crises posed unprecedented obstacles to managing restaurants in Egypt, most related to employee behaviors (Khan et al., 2023b).For instance, the negative approach to dealing with co-workers, such as bullying, gossip, ostracism, and moral harassment, whether verbal or sexual (Yang et al., 2021), is still pending to address them as they stem from the inherent friendship among close co-workers in the Egyptian restaurant context.

Procedure and data collection
The reverse translation procedure was utilized to convert the questionnaire into Arabic two weeks before data collection to fit the Egyptian dialect of full-service restaurant personnel in Greater Cairo.Subsequently, six language specialists and industry experts translated this survey into English.The primary data was collected from workers on the same shift to confirm the existence of workplace friendships.We used simple random sampling to gather data from employees at 46 full-service restaurants in Greater Cairo.We chose this sampling method for two reasons: first, it is an excellent sampling method for this research methodology because it ensures that each restaurant in the population has an equal chance of being chosen.This method improves the sample's representativeness, permitting more generalizable findings about the larger population of restaurants.
We increase the likelihood that the characteristics of the selected restaurants reflect those of the entire restaurant population by using a random sampling technique, which improves the external validity.Second, simple random sampling reduces sampling bias, which is essential in research involving restaurant employees.This method aids in the avoidance of systematic errors in the selection process, ensuring that each restaurant has an equal chance of being included.This reduction in bias contributes to our findings' validity because the sample is less likely to over-represent or underrepresent specific types of restaurants, resulting in more accurate and unbiased insights into the issues confronting restaurant employees.
This city was chosen for several reasons.First, this city is considered Egypt's capital and home to the most residents, with visitors expected from other domestic towns and touristexporting countries.Second, this city has the most significant number of full-service restaurants.Third, this city is charming; its streets and walls tell the history of the Egyptian people and their ancient civilization that has affected humanity throughout the ages.This is characterized by Egypt's most famous tourist attractions, such as the pyramids, the Sphinx, and the Cairo Tower.
Following verbal approval from restaurant management, the participants' WhatsApp groups were reached with the assistance of some restaurant managers and chefs.A link prepared for the intended questionnaire was sent to these participants via Google Forms.As a result, a time-delay approach was used to collect data across three waves.Initially, participants were informed of the need to focus on close co-workers who have the qualities of sincerity and courage and agree with them in most opinions, and vice versa.It was agreed with the participants that they should ensure that their answers related only to the friendship of the close co-worker and not to any other co-worker.Therefore, the dataset was collected for the same shift.
Although their participation was voluntary and no rewards were offered in exchange for participating, the custom author sent 46 boxes of energy chocolate to the restaurants participating in the intended survey as a noble gift for their employees after completing the data analysis process.In Wave 1, employees were questioned on the depth of their friendship with a close co-worker, and 571 responded from 10-22 October 2022.Participants were asked about their ability to talk badly about a close co-worker to another co-worker and how much they liked a close co-worker in Wave 2 from 25 October to 4 November 2022.Thus, 566 participants responded to the questionnaire items presented in this prompt.
From 9-18 November 2022, participants were asked to share their thoughts about the degree of their self-blame for the abuse they had inflicted on a close co-worker.Hence, 559 participants responded, representing Wave 3 of the data collection process.As such, outliers and missing values were checked in three waves, and a sample size free of these distorting values of 553 was reached.

Instruments
The robust validity and reliability demonstrated by each instrument in previous research drove the selection of scales in our study.For example, a 22-item co-worker friendship scale included five dimensions developed by Sias et al. (2012), as Table A1 shows.The negative gossip scale, consisting of five items (see Table A2) created by Brady et al. (2017), has demonstrated high levels of validity and reliability in capturing co-worker friendship and negative workplace gossip constructs.These scales have been widely used and validated in various organizational settings, ensuring that our study benefits from the instruments' established psychometric properties (Cortina et al., 2001).The selected scales align closely with the theoretical framework of our investigation and the specific research objectives.
The co-worker incivility scale, comprised of seven items (see Table A3) adapted from Cortina et al. (2001), has been chosen for its comprehensive assessment of uncivil behaviors in the workplace, directly addressing our focus on co-worker incivility.Likewise, the promotion focus questionnaire, comprised of seven items (see Table A4) adopted from Neubert et al. (2008), is well-suited for measuring promotion focus, a critical moderating variable in our conceptual framework.The careful selection of scales that align conceptually with our research ensures that our measurements.

Analysis strategy
Partial least-squares structural equation modeling (PLS-SEM) was chosen as the analytical approach for this paper using SmartPLS v.4.Higher-order and reflective-reflective constructs (e.g.co-worker friendship) were utilized in this paper based on PLS-SEM (Sarstedt et al., 2019).This approach does not necessitate normally distributed data and moderation effects analysis (Khan et al., 2023c).This approach may be utilized to examine the potential correlations between a set of constructs in the hospitality context (Shoukat et al., 2024).

Non-response bias and respondent characteristics
Social sciences research often has a non-response bias (Selem et al., 2023c).Findings might not be relevant if the perspectives of participants and non-participants are drastically different (Sarstedt et al., 2019).In the current paper, the non-response bias was investigated using Levene's equality variance test; valid responses in Waves 1 (313 early and 258 late responses), Waves 2 (286 early and 280 late responses), and Waves 3 (297 early and 262 late responses) were not significantly different from each other.
G*Power was run to identify an appropriate sample size (Khan et al., 2023c).Hence, an F-test with multiple linear regressions for a fixed model in G*Power 3.1 software is run with the following settings: 0.1 effect size, 0.01 error probability, 0.95 power, and eight predictors.Thus, the final sample size is adequate.Respondents' profiles showed that males comprised 53.7% and married people comprised 51.5%.Regarding age, most employees were between 21 and 29 years old (70.7%).Most respondents (47.2%) held a bachelor's degree, followed by those with a diploma (30.6%).Lastly, 36.4% of respondents had 4 to below 7 years of career experience.
Second, a single-method, single-factor strategy was used, simultaneously loading all items on their respective theoretical constructs and establishing a new mutual first-order factor.According to Table 2, this common factor can only explain 25.957% of the total variance in the first factor, while the rest of the variance was loaded on the other seven factors as follows: EJMBE negative workplace gossip (14.13%), personality (9.25%), promotion focus (5.24%), shared tasks (4.28%), similarity (3.49%), socializing (3.15%), and work/life events (2.75%).In addition, VIF was conducted in PLS-SEM to assess CMV.Because the VIF values were all less than 3.3 (see Table 1), we concluded that CMV bias did not exist in the dataset.

Co-worker friendship in restaurant
Measurement model Initially, composite reliability (CR) was performed to assess internal consistency reliability (Sarstedt et al., 2019), indicating that all CR exceeded 0.70 (see Table 1).Second, Table 2 demonstrates that all items with factor loadings exceeding 0.708 were kept.Next, the average variance extracted (AVE) values were higher than the threshold of 0.50 (see Table 1), indicating the convergent validity of all constructs.Moreover, the heterotrait-monotrait (HTMT) ratio is a more stringent discriminant validity criterion (Sarstedt et al., 2019).Hence, this ratio fell below the 0.85 cut-offs for reflecting first-and second-order measures, enhancing the model's discriminant validity (see Table 2).

Structural model
Utilizing the PLS technique, our Q 2 values were more significant than 0 (Q 2 negative workplace gossip 5 0.234 and Q 2 co-worker incivility 5 0.218).According to Chin (1998), R 2 also illustrates how much variance in dependent constructs can be explained.This model can explain 29.7 and 29.4% of the variance in negative workplace gossip and co-worker incivility, respectively.As a result, the structural model in this work was somewhat predictive.

Multi-group analysis
Our findings demonstrated compositional invariance by showing that the score of the constructs derived in one group perfectly correlated with the other group's constructs.Partial invariance was established nonetheless, as all variance scores fell within the confidence interval.Significant differences existed in the nexus of negative gossip and incivility among the two groups.Hence, the effect of negative gossip on co-worker incivility among males came to be more robust (β 5 0.509, p < 0.01) as compared with females (β 5 0.395, p < 0.01), supporting hypothesis H5 (see Table 4).This finding suggests that males react more negatively to a close co-worker's abusive reaction when talking negatively about him in his absence with other coworkers.In contrast, females may blame this co-worker for not repeating her actions.

Moderation analysis
A two-stage technique was used to calculate the moderating effect of promotion focus.Table 3 demonstrates that promotion focus significantly modifies negative workplace gossip (β 5 0.277, p < 0.01).Furthermore, the interaction effect of promotion focus 3 co-worker friendship (β 5 0.252, p < 0.01) on negative gossip is statistically significant (see Table 4).The moderation slope plot (see Figure 2) proves that the negative association between friendship and negative gossip among close co-workers is weaker when they have a higher job promotion focus and thus negatively talk about their close co-workers with less related coworkers to tarnish their image in front of others for getting job promotion.Accordingly, promotion focus dampened the co-worker friendship and negative workplace gossip relationship, supporting hypothesis H4.

Discussion
This paper examines how friendship indirectly affects incivility among close co-workers through negative gossip.We investigated the moderation effect of promotion focus in the Co-worker friendship in restaurant restaurant context.Moreover, we discussed how gender (male/female) affects the nexus between negative gossip and co-worker incivility.Over the years, workplace friendship has drawn more attention, but there has not been much study on how friendly employees are (Cheng et al., 2022;Guo et al., 2022).Our findings add significant theoretical support to the literature.
For hypothesis H1, co-worker friendship and negative workplace gossip have a negative association; our findings supported this notion, resulting in a negative relationship among coworkers on these two streams.According to AET, affective events play a significant role between the gossip target and gossipers in the workplace when gossipers disclose substantial data about the gossip target.This demonstrates how co-workers' behaviors are influenced by their emotions (Khan et al., 2023a).Employees who think others will formally evaluate them

EJMBE
become more nervous about delivering.This is because informal evaluation is comparable to involving the public (Chen et al., 2021), finally presenting a chance to build connections with co-workers and significantly increasing performance pressure (Khan et al., 2023a).Additionally, AET contributes to explaining the continued fortification of these bonds by acting as a mediator between the nasty workplace gossip and the camaraderie among coworkers.This article demonstrates how emotions influence co-workers.When getting promoted, unpleasant feelings can take center stage and lead to talking about one another, eventually portraying selfish behaviors (Cheng et al., 2022).Additionally, deviant behaviors such as unfavorable gossiping might harm co-worker incivility and undermine business performance in the hospitality context (Khan et al., 2023c).
H2 is also accepted, indicating that negative gossip negatively affects co-worker incivility.This relationship is explained through AET, which assumes that co-workers with negative emotions tend to interact with each other.In pursuit of negative workplace gossip as an event, they tend to show deviant behaviors (Guo et al., 2022), one of the major causes of poor performance in the hospitality industry (Selem et al., 2023b).Being co-workers yet of massive importance in terms of front-line workers, such types of behaviors are critical (Khan et al., 2023a), and incivility may cause severe damage to such organizational setups (Khan et al., 2023c).Furthermore, the moderation effect of gender in linking negative gossip with coworker incivility is substantial since males and females engaging in negative workplace gossip further strengthen co-worker incivility.Findings concur with those of Khan et al. (2023a), who found that workaholics are more likely to encounter more significant levels of workplace incivility.
Despite the close-fitting connection between two co-workers, gossip could be unfavorable to their interests (i.e.promotion focus).The victim of this gossip may confront the offender in various ways, depending on the gender involved.Hence, men are typically more eager to exact revenge and will do so by engaging the offender in a hostile manner, making derogatory comments in response to their co-worker's actions, or even physically and psychologically abusing them.While females are less vulnerable to each other's emotional reactions, they may only be satisfied with harsh criticism and refrain from reiterating these behaviors.This is because they believe these behaviors may have resulted from their egotism and feminism.

Theoretical implications
The interactive nature of restaurants adds new dimensions to the nexus between coworkers-both friendship and incivility.The first contribution of this paper is to advance our understanding of AET by investigating several events rather than a single event, as Chen et al. (2021) proposed.We explored interpersonal dynamics and work-related events in AET by adding psychological variables (negative workplace gossip) as an intervening variable between co-worker friendship and incivility and discovered a significant mechanism.Though AET focuses on the interaction of dispositional traits, situational factors, workrelated events, and affective responses, this paper broadens the theory by examining how interpersonal dynamics and work-related events lead to negative workplace behaviors (Khan et al., 2023a).This paper focuses on how co-worker friendship influences negative gossip and incivility among close co-workers in a restaurant setting, highlighting the complexities of workplace relationships and their impact on employee behavior.
Prior studies have shown the importance of emotions in AET, and this paper goes beyond emotions to examine how interpersonal dynamics and work-related events (i.e.co-worker friendship) contribute to negative workplace behaviors (Khan et al., 2023a).By focusing on the role of co-worker friendship in shaping workplace behaviors, this paper offers a more nuanced understanding of the factors that contribute to negative gossip and incivility in the hospitality industry.Hence, workplace gossip significantly impacts co-worker incivility Co-worker friendship in restaurant (Khan et al., 2023c;Ugwu et al., 2022).The combined effect of workshop gossip on shaping the employee behaviors of front-line restaurant co-workers in terms of their friendship-incivility relationship indicates a gap in the literature (Khan et al., 2023b).By doing so, our paper addressed this gap in the literature and contributed to a psychological theory, particularly AET.This paper's second contribution is the relatively uncommon application of AET as a standalone theory for comprehending individual behavior in the hospitality industry.AET has been widely conducted in organizational studies by previous researchers to explain employee behavior, but its use in the hospitality sector is limited (Weiss and Cropanzano, 1996).Drawing on AET, we chose gender and promotion focus as the paper's proxy factors.Restaurant settings have gained popularity as research contexts in recent decades, but little is known about the setting or its function.This study, one of the first, adds to our knowledge of the restaurant environment.

Practical implications
Our findings have several implications for restaurant owners and managers.First, our results have some applications that can assist organizations and workers in managing friendships at work.To begin with, workers should understand that although friendships at work offer many advantages and can significantly improve our professional lives, they also carry some risks and negative consequences.Employees must be aware of the drawbacks of workplace friendships to manage their social relationships at work.To achieve this, it might be crucial to establish guidelines for professional interactions with co-workers.For instance, demonstrating that it is a part of one's professional duty to challenge one another in meetings can ease worries about offending a co-worker.
From a practitioner perspective, restaurant managers should explicitly design the local operating instructions (LOPs) for the restaurant's front-line personnel to talk and exchange positive information about co-workers while avoiding negative information about irrelevant activities during working hours.As a result, restaurant managers should implement a "zero tolerance" policy for disseminating public gossip.Providing timely and comprehensive information sharing and creating efficient channels for information exchange, such as holding frequent team meetings, setting open door rules, and promoting candid and open discussion to reduce negative gossip.
Further, restaurant managers should use an informal approach, such as fostering a warm, transparent, and inspiring workplace, rewarding and praising positive behavior, and offering professional and career growth opportunities.Moreover, managers may provide prompt psychological treatment to people who have been the targets of unfavorable workplace gossip.For instance, managers can refute rumors about them openly to give a particular employee their right to paid vacation.
Lastly, our findings suggest that pleasant co-worker friendships among front-line restaurant employees can lower incivility.Co-worker friendship is a modern phenomenon in the hospitality industry.Managers can devise measures to reduce uncivil employee conduct by establishing a healthy social environment in restaurants.This may be accomplished if managers develop and implement additional abilities to foster workplace friendship.For instance, restaurant managers should organize personality enhancement training programs and counseling to deal with challenges and workplace stress.

Limitations and future research
The current paper, like previous ones, has a set of research limitations.First, the research sample consisted of front-line employees, and we employed a time-lagged technique in three separate waves to control for CMB.The same respondents measured the significant components.However, such biases may still impact our findings (Selem et al., 2023b).Respondents are likely swayed by social desirability and may struggle to respond honestly since workplace gossip and co-worker incivility are sensitive issues.Future researchers may employ other research designs, such as multi-source data (supervisors and co-workers).Moreover, although our study does not explicitly measure emotions, we believe emotions are intrinsically linked to the studied notions.Negative workplace gossip, for example, can elicit various emotional reactions, and co-worker incivility is probably affected by the emotional states of those engaged.However, we recognize that further study may explicitly explore these categories' emotional aspects and interactions in greater detail according to the AET principles.

Conclusion
This paper's purpose was to investigate the potential hazards and consequences of workplace friendships among co-workers, how they affect office rumors, and how gossip affects coworker impoliteness.Furthermore, the mediating function of unfavorable workplace rumors in the linkage between co-worker friendship and incivility was examined.The current study focuses on how promotion focus moderates the nexus between workplace incivility and friendship.Promotion-focused orientation has been tested as a mediator between co-worker friendship and incivility among co-workers.By helping develop interpersonal skills and team-building activities that support these positive relationships, managers can create a friendly and supportive workplace that improves their work culture and eliminates incivility.
