Job crafting promotes internal recovery state, especially in jobs that demand self-control: a daily diary design

Research on how employees recover from work has focused primarily on recovery during non-work hours (external recovery) rather than recovery during work hours (internal recovery). Using the conservation of resources theory as a conceptual framework, we tested whether job crafting promotes an internal recovery state, and examined the processes that explain this association.Using the daily diary method, 120 full-time employees provided information before and after work for 5 days by rating job crafting, ego depletion, self-control demands at work, fatigue and vigor.The results of multilevel modeling showed that after controlling for employees' fatigue and vigor before work, daily job crafting predicted significantly better internal recovery (greater vigor and lower fatigue at the end of workday), and this association was mediated by lower ego depletion. The links between job crafting and internal recovery were stronger for employees with high self-control demands at work.This study extends recovery research by examining internal recovery as well as job crafting as its antecedent. Further, the present study suggests that managers may consider encouraging and offering job crafting interventions for employees to achieve internal recovery state.
