Recommendation systems are a fundamental tool for hotels to adopt a differentiating competitive strategy. The main purpose of this work is to use machine learning techniques to treat imbalanced data sets, not applied until now in the tourism field. These techniques have allowed the authors to analyse the influence of imbalance data on hotel recommendation models and how this phenomenon affects client dissatisfaction.

An opinion survey was conducted among hotel customers of different categories in 120 different countries. A total of 135.102 surveys were collected over eleven quarters. A longitudinal design was conducted during this period. A binary logistic model was applied using the function generalized lineal model (GLM).

Through the analysis of a representative amount of data, the authors empirically demonstrate that the imbalance phenomenon is systematically present in hotel recommendation surveys. In addition, the authors show that the imbalance exists independently of the period in which the survey is done, which means that it is intrinsic to recommendation surveys on this topic. The authors demonstrate the improvement of recommendation systems highlighting the presence of imbalance data and consequences for marketing strategies.

The main contribution of the current work is to apply to the tourism sector the framework for imbalanced data, typically used in the machine learning, improving predictive models.

Guided by the cognitive-affective system theory of personality (CAPS), this study aims to investigate the parallel mediating effects of cognitive and affective cynicism on the relationship between illegitimate tasks and employees’ adaptive performance. It also proposes growth need strength as a moderating variable for relationships between illegitimate tasks and employees’ adaptive performance.

Using a time-lagged design, data were gathered from 330 frontline hotel employees in China.

The authors found that the presence of illegitimate tasks is negatively associated with employees’ adaptive performance, this relationship being mediated by cognitive and affective cynicism. Growth need strength weakens the negative impacts of cognitive and affective cynicism on employees’ adaptive performance. In addition, the indirect effect of illegitimate tasks on employees’ adaptive performance via cognitive and affective cynicism is stronger for employees with lower levels of growth need strength.

Hotel managers must heed the negative impact of illegitimate tasks. Furthermore, they should underscore the importance of promoting a harmonious and positive organizational culture and atmosphere. Naturally, hotel managers must also establish effective communication with employees, assisting them in fostering a desire for excellence in their work.

This study provides valuable insights for the hospitality industry by investigating how illegitimate tasks hold sway over hotel employees’ adaptive performance. The study uses a moderated dual-path model to uncover the mechanisms behind this impact and the influence of boundary conditions, thereby expanding the understanding of the topic.

The ever-demanding role of employees in the hospitality sector stimulates job crafting. This study examines the relationship between inclusive leadership and job-crafting dimensions under the mediating role of work engagement through the lens of conservation of resources (COR) theory. It also aims to analyse the boundary condition of job autonomy between inclusive leadership and work engagement.

The data were collected in 3-time lags from 319 front-line workers in the hospitality sector. The adopted and adapted questionnaires were executed through a deductive approach and an applied research method. The data were analysed through SmartPLS by applying the structural equation modelling (SEM) technique.

This study provides evidence for a predictive relationship between inclusive leadership and job-crafting dimensions under the mediating psychological mechanism of work engagement. Additionally, the moderating role of job autonomy is established in the unique context of the hospitality sector of an underdeveloped country, Pakistan.

Services-based organisations need to endure the inclusive leadership style by establishing work engagement practices. Engaged employees result in better job-crafting behaviours through better training and subsequent performance.

This study established that work engagement and job autonomy are imperative forces that impact the relationship between inclusive leadership and job-crafting dimensions. The research study has time-lagged data and conveys meaningful theoretical and practical implications.

This study examines how leaders’ narcissistic rivalry (LNR) affects the in-role performance (IRP) and proactive customer service performance (PCSP) of employees in the hospitality industry. Specifically, this study investigates the mediating role of psychological distress and the moderating role of locus of control (LOC) in the aforementioned relationships.

This study administered a multi-wave, multi-source questionnaire survey with 323 employees working in 11 full-service hotels in China. Statistical analyses were performed using the PROCESS macro in SPSS 26 software and structural equation modeling using Mplus 8.3 software.

The authors' results suggest that LNR can negatively affect hospitality employees’ IRP and PCSP and that these relationships are mediated by psychological distress. Additionally, the impact of LNR on psychological distress can be lessened by internal LOC.

This study contributes to the literature on leader narcissism by investigating how LNR affects IRP and PCSP among hospitality employees. Drawing on conservation of resources theory, this study also identifies a novel mediating mechanism (psychological distress) connecting LNR to hospitality employees’ service outcomes. Furthermore, this study reveals the moderating role of LOC in the relationship between LNR and psychological distress.

Undertaking the theoretical lens of “The need to belong” theory, the present study intends to explore the aftermath of internal whistleblowing and the behavioral outcomes that follow by linking it to the literature on workplace ostracism, loneliness and intentions to quit.

The respondents were hotel employees in the Delhi NCR region of northern India. A hypothesized sequential mediation model was tested on a sample of employees from a hotel using a three-wave time-lagged multistudy design.

The findings of the study established that internal whistleblowing leads to intentions to quit via workplace ostracism and loneliness at work.

The unique contribution of this study lies in understanding the underlying mechanisms and discussing the behavioral outcomes that follow post-whistleblowing. HR managers need to develop a work environment that protects whistleblowers and has a zero-tolerance policy against employees engaging in any form of retaliation or unethical business practices. Managers must be more proactive and sensitive to the social cues that will make them aware of the presence of acts of ostracism. Upon encountering such acts, managers can consider counseling employees engaging in such unhealthy practices.

The present research aims to empirically test the “Barriers to abusive supervision model” to find how employee-related (core self-evaluations) and situational factors (perceived job dependency) make an employee trapped in the spiral of supervisory abuse. In addition, the work–family spillover lens is used to explain how employees' retaliation is targeted at their families in response to abuse from their bosses.

The current study has employed a three-wave longitudinal moderated mediation design and analysed data from 265 employees working in the hospitality industry of Pakistan.

The results of this study have shown that low core-self evaluations put employees in a spiral of supervisory abuse and they instil aggression towards their families. This association is further strengthened when employees are dependent on their job.

This study is one of the first to use the “Barriers to Abusive supervision” model to answer who and in which conditions tend to trap in the spiral of abuse and integrate the work-to-family interface model for elaborating the outcomes to the family domain.

This research aims to extend the research on humorous leadership and the hospitality industry by using the theoretical framework of affective events theory (AET). This research aims to close this gap by recognizing that leaders' humor may inspire pro-social motivation in tourism workers and can harness the ability of employees to offer innovative ideas. The effect of leaders' humor on employees’ pro-social motivation is moderated by the personal need for structure (PNS).

A multi-source time-lagged design was employed in this research. The researchers used survey instruments to collect data from frontline employees and their immediate supervisors working in Pakistan’s two- to five-star hotels. The current study considers 279 useable responses and tested them through Hayes process macros.

Results show that humorous leadership has a significant direct impact on the innovative work behavior (IWB) of hotel employees. Pro-social motivation significantly mediates the relationship between humorous leadership and IWB. Further, the PNS significantly buffers the relationship between humorous leadership and pro-social motivation.

Findings are vital for hotel managers to adopt a more flexible leadership style to promote the pro-social motivation and IWBs of hotel employees.

This is one of the first studies to use pro-social motivation to explain the relationship between humorous leadership and creative work behaviors. Employees' individual needs for structure have also been utilized as a novel boundary condition. The results are essential for hotel managers to adopt a more adaptable leadership style to encourage the staff’s pro-social motivation and creative work behaviors.

Taking the support of social capital theory and conservation of resource theory, the present study explores the mediating role of rumination and moderating role of mindfulness in the relationship of workplace ostracism (WO) and workplace withdrawal (WW).

The data were collected in two waves from 467 employees working in hotels located in Delhi NCR region of India. The hypothesised relationships were investigated by macro-PROCESS (Hayes, 2013).

The results found a mediating impact of rumination on WO and WW relationship. It further supported the moderating effect of mindfulness in weakening the association between WO and WW via rumination.

This study identified mindfulness as an essential mechanism by which WO may be regulated to control employee's tendency to ruminate. Rumination may initially be prevented in organisations by regulating the primary effect of WO on employees' decisions for WW.

By linking the research model with the social capital theory, the study has contributed to the existing body of knowledge. The study is the first of its kind in India to examine the impact of hypothesised associations on the hotel industry. The findings of the study would help the industry in understanding the role of mindfulness in reducing aberrant behaviours at workplace.

The authors intended to find out what motivates employees at the workplace. For this purpose, the authors examined family motivation and intrinsic motivation influences over work attitudes such as organizational citizenship behavior (individual) and affective commitment.

In the current research, the authors adopted time-lagged approach to collect a total of 352 responses from managers in the hospitality sector. This approach was adopted to avoid common method issues related to survey research.

The findings suggest positive association of family motivation with intrinsic motivation, affective commitment and organizational citizenship behavior (individual). The authors also found intrinsic motivation positively related to affective commitment and organizational citizenship behavior (individual). The findings also found statistical support pertaining to the mediating role of intrinsic motivation on family motivation's positive relationship with affective commitment and organizational citizenship behavior (individual).

Considering important role of family motivation, the authors ask managers to think through ways that could help employees feel better about their family's wellbeing. The authors also suggest organizations upsurge intrinsic motivation of their employees by engaging them in decision-making process, allow employees to craft their jobs because through these a higher level of organizational citizenship behavior for individuals and affective commitment could be generated.

The authors extend the core assumption of self-determination theory that work motivation (intrinsic in specific) is autonomously determined, deeply rooted within individuals, and gratifying. It works on the pleasure principle and mirrors a hedonic standpoint. In such a situation, employees work merely based on their interest and joy; they focus and enjoy the process.

This paper aims to explore the impact of ebullient supervision on thriving at work, and relational social capital to stimulate employee creativity in the hospitality industry.

Using a purposive sampling approach, data were collected from 391 subordinates and their immediate supervisors in the hospitality industry through a structured questionnaire. To analyze the data, partial least structural equation modeling approach was considered.

Results show that ebullient supervision is supportive in generating personal resources of thriving at work and relational social capital, which later shape employee creativity.

The empirical findings of this study provide valuable insights for managers in the hospitality industry for human resource development strategy formulation to stimulate creativity in the hospitality industry.

The findings of this study suggest a novel antecedent of ebullient supervision for stimulating creativity in the hospitality industry. Hence, the paper has implications for researchers, practitioners and students.
