Determinants and consequences of job crafting under the boundary conditions of work uncertainty

Purpose - This paper explores critical job resources (CRJRs) as predictors of job crafting and sustainable employability. Using job demands-resources (JD-R) theory as a theoretical lens, the authors examine how job crafting mediates CRJR and sustainable employability and whether work uncertainty as a boundary condition further strengthened these associations using moderated mediation approach. Design/methodology/approach - The authors used a cross-sectional time-lagged research design by collecting data from 483 knowledge workers in Pakistan's healthcare and universities, both public and private. The authors used structural equation modeling using AMOS 25.0 software to examine the proposed relationships ' mediation, moderation and moderated-mediation processes, such as Hayes (2018) process models 1,7,14 and 58. In addition, the authors tested a structural model with self-developed estimands instead of using process macros available in SPSS by computing variables. Findings - The results of this study confirmed that CRJR predicts job crafting and employees ' sustainable employability. Furthermore, comprehensive testing suggested that mediation of job crafting between CRJR and sustainable employability further strengthened in the presence of a boundary condition of work uncertainty. Originality/value - The study uncovers CRJR (job, organizational, social and relational) as a predictor of job crafting. The authors suggest that job design integrating CRJR helps organizations and managers promote job crafting and make employees responsible for their sustainable employability. The proposed CRJR has not been used as a predictor of job crafting, and no such study tested CRJR as a predictor of sustainable employability. The authors made comprehensive testing to examine the boundary condition of work uncertainty while examining the CRJR and sustainable employability relations via job crafting.
