Abstract Introduction In the context of the COVID-19 pandemic, pharmacists, despite their vital contributions, have faced significant challenges that have impacted their mental well-being, potentially leading to the development of Post-Traumatic Stress symptoms (PTSS). The aim of this study was to investigate the role of work-related fatigue as a potential moderator in the relationship between pharmacists’ resilience and their likelihood of experiencing PTSS during the COVID-19 pandemic. Methods A cross-sectional survey was conducted online in eight countries from January to December 2021, including Brazil, Lebanon, Nigeria, Pakistan, Poland, Serbia, and Tunisia. The mediation analysis was conducted using PROCESS MACRO (an SPSS add-on) v3.4 model 1, taking work fatigue as a moderator in the association between resilience and PTSS. Results A total of 442 pharmacists were enrolled in this study (mean age = 33.91 ± 10.36 years) with 59.5% of them being females. The results were adjusted over country, gender, working in contact with COVID-19, working patients, working mandatory hours, working voluntary hours, age, household crowding index and number of months engaged in COVID-19. The interactions resilience by physical (Beta = 0.02; p = .029), mental (Beta = 0.02; p = .040) and emotional (Beta = 0.03; p = .008) work fatigue were significantly associated with PTSS; for pharmacists with low to moderate levels of physical (Beta = − 0.33; p < .001 and Beta = − 0.21; p = .001), mental (Beta = − 0.29; p < .001 and Beta = − 0.18; p = .006) and emotional (Beta = − 0.31; p < .001 and Beta = − 0.17; p = .008) work fatigue, higher resilience was significantly related to lower PTSS levels. However, for pharmacists with high levels of physical/mental/emotional work fatigue, the association between resilience and PTSS became non-significant. Conclusion This study highlights the complex relationship between work-related fatigue, resilience, and PTSS in pharmacists. It emphasizes the need to address work-related fatigue for pharmacists’ psychological well-being during crises, offering insights for tailored support and interventions.
