The aim of the research is to investigate the influence of leadership on firm financial performance and to explore the mediating role of employees' readiness to change.

The paper hypothesizes that employees' readiness to change mediates the relationship between leadership and firm financial performance. A total of 213 employees of Greek shipping firms completed questionnaires examining their firms' leadership style and concurrently, their supervisors appraised their readiness to change. The research model was tested with the use of Structural Equation Modelling.

The research findings note the importance of leadership in fostering firm financial performance; they describe how each leadership style influences employees' readiness to change; as well as, they confirm that employee readiness mediates the relationship between leadership and firm financial performance. Theoretical and practical implications of these findings are analysed.

Given that the research was conducted during the severe Greek economic crisis, a time when employees' behaviour is highly influenced by distinctive and complex internal and external relationships, there is scope for further work to verify that the relationships identified in this study remain valid during periods when market conditions are more favourable.

The findings provide further support on the significance of employees' readiness to change and the paper suggests policies for its development.

The originality of this study lies in the finding that employees' readiness to change mediates the relationship between leadership and firm financial performance. Further, the study was carried out in Greek shipping industry that plays a vital role in the international shipping industry which is responsible for the carriage of around 90% of world trade.

Both uncertainty reduction theory and uncertainty management theory suggest that uncertainty reduction during organizational change is imperative as it may influence positively employees’ attitudes and behaviors. By drawing on the theory of planned behavior that links individual’s beliefs and behavior, the study seeks to examine how employees’ self- and other-interest in change may reduce perceptions of change uncertainty and consequently, foster their behavioral change support (i.e. compliance, cooperation and championing).

The study hypothesizes that employees’ self- and other-interest in change mediate the relationship between perceptions of change uncertainty and behavioral change support. The research was conducted in two large IT companies co-located in a big science park in an EU country in South-eastern Europe. Data were collected from 105 employees and their supervisors in three sequential phases.

The research findings suggest that both self- and other-interest in change partially mediate the negative relationship between perceptions of change uncertainty and behavioral change support.

The findings indicate that change management practitioners will benefit considerably if they try to decrease employees’ perceived change uncertainty by increasing their self- and other-interest in change to provoke supportive behaviors. Relevant suggestions are made.

The findings provide new insights into how perceptions of change uncertainty and self- and other-interest in change can affect employees’ change participation. Further, the research findings add to the uncertainty reduction theory and uncertainty management theory as well as, other related notions.

Based on the job demands-resources theory, the objective of the current research is to investigate the influence of contextual (i.e. change information), as well as, personal (i.e. meaning-making) change resources on the perceived change uncertainty (PCU) and employee burnout (i.e. emotional exhaustion, cynicism, professional efficacy) relationship.

The paper examines (1) whether PCU is related to burnout, (2) the extent to which change information and meaning-making are directly associated with burnout and (3) whether change information and meaning-making moderate the relationship between PCU and employee burnout. The research data were collected (in three sequential phases) from 293 employees of a group of Luxury Hotels and Resorts located in Southern Greece that has undergone a major cultural change.

The research findings suggest that change information is related to exhaustion and cynicism, as well as, that meaning-making is directly related to all of the burnout components. Change information buffered the negative relationship between PCU and exhaustion and between PCU and cynicism. Meaning-making moderated the negative relationship between PCU and exhaustion.

The results support that leaders and managers will benefit significantly if they realize how important is to ensure that these change resources (i.e. change information and meaning-making) are in place during organizational changes and constantly evaluate the factors that can increase their employees’ well-being.

The originality of this study lies in the finding that change information moderated the negative relationship between PCU and exhaustion, as well as, PCU and cynicism; and that meaning-making moderated the negative relationship between PCU and exhaustion. Further, the study refers to the Greek tourism industry (9th in the word in terms of international tourist arrivals) which plays a pivotal role to the Greek economy. Finally, the research findings contribute to the uncertainty reduction theory, as well as, other related notions.

By drawing on the need to belong theory, the paper aims to propose a moderated mediation model to examine the role of workplace belongingness and meaning-making in the positive relationship between inclusive leadership and employee change participation.

Participants were 155 employees from 31 teams from a branch of a multinational pharmaceutical company located in an EU country. The company faces constant legal, regulatory and technology-related changes after the coronavirus disease 2019 (COVID-19) pandemic outbreak. Data were collected in three waves, approximately three weeks apart between March 2020 and May 2020. To test the mediating effect of workplace belongingness were performed first – a series of regression analyses – and second, bootstrapping to assess the statistical significance of the indirect effect (Preacher and Hayes, 2008).

Workplace belongingness mediates the relationship between inclusive leadership and employees change participation. Further, the research findings provide support that meaning-making moderates the relationship between workplace belongingness and change participation as well as the indirect relationship between inclusive leadership and change participation through workplace belongingness such that the positive relationships are stronger when meaning-making is higher.

The results indicate that should leaders and change management practitioners manage to influence positively employees' workplace belongingness by employing inclusive practices and procedures; leaders and change management practitioners will increase the level of participation during change and further the results note from an applied perspective the importance of mean-making as a facilitating factor during change in organizational settings. Relevant suggestions are made.

The findings provide new insights into how inclusive leadership and workplace belongingness can affect employees' change participation. Further, the research findings note the significant moderating role of meaning-making regarding both the relationship between workplace belongingness and change participation as well as the indirect relationship between inclusive leadership and change participation through workplace belongingness.

By drawing on the perceived organizational support (POS) theory and the extended job demands-resources model (JD-R model), the aim of this study is to investigate the influence of different levels of organizational support during change (i.e. organizational level, supervisory level, coworker level) on firm financial performance and to explore the role of employee work engagement.

Data were collected during the second outbreak of the COVID-19 pandemic in two waves, approximately 2 weeks apart. A total of 291 employees in the Greek telecommunication industry completed questionnaires examining the POS during change and consequently, their supervisors evaluated their work engagement. The research model was tested with the use of structural equation modeling.

The research findings note the importance of different levels of organizational support during change; they describe how each level influences employees' work engagement as well as they confirm that employee work engagement mediates the relationship between POS during change and firm financial performance. Theoretical and practical implications of these findings are discussed.

The results indicate that should firms manage to influence positively employees' work engagement by providing support at all levels during change, they may boost their financial performance.

The research findings provide new insights into how POS and work engagement may influence firm financial performance. The originality of this study lies in the finding that employees' work engagement mediates the relationship between POS during change and firm financial performance. Further, the study was carried out in the Greek telecommunication industry during the second outbreak of the COVID-19 pandemic.

The aim of the research is to investigate how managers' personal traits, emotions and attitudes shape their tolerance of ambiguity (TOA); and consequently, the influence of managers' ambiguity tolerance in organizations' financial performance.

Survey data were collected from 54 Greek banks. A total of 412 senor-level managers completed questionnaires examining TOA, personal traits, emotions and attitudes in the workplace. Principal components analysis and ordinary least-squares regressions were used to explore the hypotheses of the paper.

Three factors characterize managers' emotions in the workplace, namely pleasure, arousal and dominance; and, respectively, two factors their involvement, namely importance and interest. Further, locus of control, importance, job satisfaction, pleasure and organizational commitment critically affect managers' TOA, which, in turn, seems to influence positively organizations' profitability.

Further research is required in Greek banking industry regarding the influence of managers' emotional and cognitive attributes in organizations' financial performance. Likewise, this research should be expanded to other industries.

The findings provide further support on the significance of emotional and cognitive attitudes in the workplace; the paper suggests policies to enhance managers' TOA, and thus, organizations' profitability.

The originality of this study lies in the finding that emotional and cognitive characteristics affect managers' TOA, which, in turn, influences significantly organizations' profitability. Another significant contributing factor is that the study is carried out in Greece, where few studies have been conducted in this area.

The aim of this research is to investigate the influence of hybrid knowledge management in workers' productivity and tolerance of ambiguity.

The research was conducted before and after the implementation of the Communication and Knowledge Motivator (CKM) model in Hellenic Railways Organization (2004 and 2008). Survey data were collected from 352 workers. In the first phase (2004), workers' productivity, ambiguity tolerance and demographical characteristics were examined. In the second phase (2008), the same measurements were performed. Ordinary regressions (enter and stepwise) were used to explore the research hypotheses.

The paper finds that workers' productivity and tolerance of ambiguity is positively affected by the CKM model. Further, it confirms the significant influence of workers' ambiguity tolerance in their productivity, before and after the implementation of the CKM model.

Workers' productivity might be influenced by the Hawthorne effect or by other emotional/cognitive attitudes. There is no such earlier measurement in Greece to compare and appraise the research findings and overall, the CKM model. Further research needs to be conducted in the Greek public sector.

The research findings suggest that the CKM model affects positively workers' productivity and ambiguity tolerance. Additionally, they note that workers' tolerance of ambiguity affects significantly their productivity.

The originality of this study lies in the CKM model that may influence positively workers' productivity and ambiguity tolerance. The study was carried out in Greece where few relevant studies have been conducted.

Drawing from uncertainty reduction theory and uncertainty management theory, the aim of the research is to investigate the influence of positive change orientation (i.e. change self-efficacy, positive attitudes toward change, perceived control) on the perceived change uncertainty and behavioral change support (i.e. compliance, cooperation and championing) relationship.

The paper hypothesizes that employees' positive change orientation partially mediates the relationship between perceived change uncertainty and behavioral change support. The research data were collected from employees and their supervisors in three sequential phases. The research model was tested with the use of Structural Equation Modeling.

The research findings suggest that employees' change self-efficacy and attitudes toward change partially mediates the negative relationship between perceived change uncertainty and behavioral change support.

The results support that change management practitioners will benefit significantly if they manage to influence their employees' positive change orientation as well as to decrease the perceived uncertainty to provoke change supportive behaviors. Relevant suggestions are made.

The originality of this study lies in the finding that employees' change self-efficacy as well as their attitudes toward change partially mediates the relationship between perceived change uncertainty and behavioral change support. Further, the research findings add to the uncertainty reduction theory and uncertainty management theory as well as other related notions.

By drawing on the reciprocity norm and the employee engagement theory, the aim of this study is to investigate the influence of workplace characteristics (e.g. individual, job, group and organizational levels) on remote employee work performance (i.e. task, adaptive and proactive) and to examine the potential role of work engagement.

Data were collected through a phased investigation in a branch of a multinational telecommunication company located in Greece. The research was carried out from September 2022 to December 2022. Firstly, 364 exclusively remote employees completed questionnaires examining work-related characteristics (i.e. change self-efficacy, work autonomy and perceived organizational support (POS)) as well as their work engagement. Consequently, their supervisors evaluated their work performance. The research model was tested with the use of structural equation modeling (SEM).

The research findings suggest that change self-efficacy, work autonomy, support from supervisors and organizational support positively influence employee work engagement as well as that work engagement mediates the relationship among change self-efficacy, support from supervisors, organizational support and employee work performance (i.e. task and adaptive). Theoretical and practical implications of these findings are discussed.

The results indicate that if organizations manage to influence positively their employees’ work engagement by providing them with the necessary conditions and support (i.e. individual, group and organizational levels), they may increase their work performance in changing and complex times.

The research findings provide new insights into how workplace characteristics and work engagement may influence employee performance during turbulent times. The originality of this study lies in the finding that employees’ work engagement mediates the relationship among change self-efficacy, support from supervisors, organizational support and employee work performance (i.e. task and adaptive). Further, the study refers to exclusively remote employees, and it was conducted in the meta coronavirus 2019 (COVID-19) era.

The aim of the research is to investigate the influence of emotional attitudes towards change on managers' tolerance of ambiguity.

A total of 70 CEOs of Greek IT firms completed questionnaires examining tolerance of ambiguity, emotional attitudes towards change ambiguity and job satisfaction. Principal components analysis and ordinary regression analyses were used to explore the hypotheses.

The paper finds that three factors characterize managers' emotional attitudes towards change, namely dominance, arousal, and pleasure. Furthermore, it indicates that job satisfaction can be taken as a critical intervention variable that “energizes” managers' arousal (i.e. stimulation, excitement and frenzy) which, in turn, influences their tolerance of ambiguity.

Deeper and broader level of research is necessary in Greek IT industry regarding the influence of emotional attitudes on tolerance of ambiguity. Likewise, this research should be expanded to other industries.

The findings provide further support on the significance of emotional attitudes during change and the paper suggests policies to enhance managers' tolerance of ambiguity.

The originality of this study lies in the finding that job satisfaction energizes the arousal factor, which, in turn, influences significantly managers' tolerance of ambiguity. Another important contributing factor is that the study is carried out in Greece, where few studies have been conducted in this area.
