Purpose 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. Design/methodology/approach 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. Findings 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. Originality/value 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.
