The purpose of this paper is to discuss relationships between high-performance work systems (HPWSs) and productive/counterproductive behaviours initiated and performed by employees. Using the ability, motivation and opportunities (AMO) theoretical framework, the authors described how an HPWS influences employee behaviours. The authors suggest that HPWSs could increase productive work behaviour and decrease counterproductive behaviours by mediating employees' affective commitment and moderating their self-efficacy.

This study is based on data from 563 questionnaires, which were completed using the computer-assisted telephone interview method. The respondents were knowledge workers, representing companies of various sizes in the Knowledge-Intensive Business Service (KIBS) sector in Poland. Statistical verification of the mediation and moderation analyses was conducted with macro PROCESS (ver. 3.3).

This research confirmed a significant statistical relationship between all examined variables. It has been shown that HPWSs influence productive and counterproductive behaviours both directly and indirectly through mediation of affective commitment. The statistical analysis also confirmed the study’s hypothesis that self-efficacy moderates relationships between an HPWS and employee behaviours.

This study has two limitations: its cross-sectional design and the use of self-reported questionnaire data.

This study is the first to explore mediating mechanisms between HPWSs and employee performance in the context of the KIBS companies in Poland. The results indicate that HPWSs are important antecedents of productive and counterproductive behaviours among knowledge workers.

Drawing on the job demands-resources theory (JD-R), this study aims to discuss the relationship between paradoxical leadership and job crafting (approach and avoidance), considering the moderating role of overwork climate and organisational identification in two cultural context (China and Poland).

The research was conducted on employees from diversified organisations in two different cultural context: China (N = 408) and Poland (N = 400). Statistical verifications of the three-way interaction effect were conducted with Jamovi version 2.3 and multigroup analysis with SPSS AMOS version 29.

The results showed that employees who perceive high levels of paradoxical leadership and overwork climate as well as possess a high level of organisational identification engage stronger in job crafting, both approach and avoidance. Moreover, the results demonstrated that the dimensions of culture: individualism-collectivism moderate the relationship between the variables tested, in such a way that the relationship is stronger with the lower level of individualism.

This study has two limitations: its cross-sectional design and the use of self-reported questionnaire data.

The study expands knowledge of the relationship between paradoxical leadership and job crafting in two different cultural contexts.

Drawing on the job demands-resources theory, this study investigates the mediating role of job satisfaction and the moderating roles of abusive supervision and perceived organisational support (POS) in the relationship between perception of organisational politics (POP) and employee job performance. This study hypothesised that employees with high POS and low abusive supervision can function effectively even in organisations with a high level of organisational politics.

The study was conducted anonymously on 408 employees, from companies operating in Poland which were completed using the computer-assisted telephone interview method. Statistical verifications of the moderation and mediation analyses were conducted with PROCESS macro.

The results showed that a high level of POP does not diminish employee performance when employees perceive low levels of abusive supervision and a high level of POS. Furthermore, the results revealed that job satisfaction mediates between POP and employee performance.

This study integrated research on politics, abusive supervision and POS to examine the collective impact of these variables on employee performance. The findings have important implications in terms of the potential buffering that can be applied to reduce the negative impacts resulting from POP.

The purpose of this study was to describe and explain the relationship between job burnout (JB), organisational citizenship behaviours (OCBs) and counterproductive workplace behaviours (CWBs). The job demands-resources theory was applied to test the moderating role of perceived organisational support (POS) in the relationship shared by JB, OCBs and CWBs.

The study was conducted anonymously on a group of 253 telephone customer support services employees from companies operating in Poland. Moderation analyses for statistical verification were conducted with macro PROCESS version 3.3.

The research confirmed a significant statistical relationship between JB and all the studied variables: POS, OCBs and CWBs. It may be concluded that JB increases the probability of CWBs and decreases employee readiness for OCBs. When employees experienced POS, a reduction in tendency for counterproductive behaviours was observed, while citizenship behaviours remained unchanged. Thus, it might be concluded that POS levels off the intensity of the influence of JB on employees’ organisational behaviours.

Individuals who lack enough social resources to perform their job tasks limit their citizenship activity in the workplace within their behavioural strategy (helping, initiative, etc.). In order to protect their resources, they may also display strategies that are destructive for their organisational environment, e.g. incivility or production deviance. In the situations when the organisation and superiors provide employees with support and demonstrate concern for providing comfortable working conditions, such persons, even in the case of perceived emotional exhaustion, maintain a high level of job activity.

The combination of variables presented in the research model explains the significance of the chosen determinants of behaviours that are key from the perspective of the organisation’s effectiveness and market competitiveness. This research extends knowledge pertaining to the relationship between JB and organisational behaviours.

The purpose of this paper is to describe and explain the manner in which HR system’s flexibility, in combination with employees’ individual flexibility (IF) and their positive character traits, such as: optimism, hope, resistance or self-efficacy (which comprise psychological capital (PsychCap)), allow to predict employees’ readiness to display innovative behaviors in the workplace.

A quantitative research methodology was adopted which resulted in the development of a both self-administered online survey instrument (n=166) and employees students in the postgraduate program at the Warsaw School of Economics (n=70). Using a national database of service companies, a random sample of 700 e-mail addresses was generated and respondents were invited to participate in the online survey. This resulted in the completion of 166 online surveys, representing a response rate of 26 percent. The second group of respondents consisted of 70 employees from different organizations in Poland.

On the basis of the analyses it was shown that HR flexibility (HRF) and IF are a generally weak predictor of innovative behaviors. However, in a situation when PsychCap is set to be a mediator, these variables allow to predict innovative work behavior.

Research on the relation of HRF to innovative behaviors has not been sufficiently clarified so far. The achieved results shed new light on the relations of these two variables and indicate that HRF does not translate directly into behaviors of the personnel. However, it should be noted that the relationship of these variables are of indirect nature.

The purpose of this study is to describe and explain the relationship between perceived social-organizational climate (PSOC), organizational citizenship behaviors (OCB) of other employees and innovative workplace behaviors (IWB) initiated and performed by employees. The mediating role of person-organization fit (P-O Fit) is tested within the relationship of PSOC, OCB and IWB.

The study was conducted anonymously on a group of 246 employees from 76 companies operating in Poland. Structural equation modeling (SEM) was used in the process of statistical analysis.

The research confirmed a significant statistical relationship between IWB and all studied variables: PSOC, OCB and P-O Fit. On the basis of the analysis, using SEM, it may be concluded that PSOC and OCB of other employees have an indirect influence on IWB, via P-O Fit.

A cross-sectional design and use of self-reported questionnaire data are limitations of this study.

The combination of variables presented in the research model may explain the significance of the chosen determinants of behaviors which are the key ones from the perspective of the company’s effectiveness and competitiveness on the market. The results of this research extend the knowledge in the area of relationships of innovation in the workplace with aspects of social functioning in the organization.

This study proposes to develop and investigate different iterative solvers for non‐Newtonian flow equations.

Existing approaches for the time discretization of the flow equation and for an iterative solution of the discrete systems are discussed. Ideas for further development of existing preconditioners are proposed, implemented and investigated numerically.

A two‐level preconditioning, consisting of a transformation of the original system in the first step and subsequent preconditioning of the transformed system is suggested. The GMRES iterative method, which usually performs well when applied to academic problems, showed dissatisfactory performance for the type of industrial flow simulations investigated in this work. It was found that the BiCGStab method performed best in the tests presented here.

The iterative solvers considered here were investigated only for a certain class of polymer flows. More detailed studies for other non‐Newtonian flows should be carried out.

The work presented in this paper fills a gap related to the usage of efficient iterative methods for non‐Newtonian flow simulations.
