Time theft represents an inconspicuous yet pervasive form of unethical misconduct in the workplace, engendering significant losses for organizations. It is thus incumbent upon companies to take measures to mitigate such conduct. Human resource management (HRM) constitutes a pivotal approach through which organizations can regulate employee actions and curb organizational misconduct; however, its role has been largely underexplored in the extant literature. Recognizing the moral foundations of socially responsible HRM (SRHRM), we synthesize signaling theory with cue consistency theory to posit (...) that SRHRM exerts a negative influence on employee time theft via enhanced moral awareness. Furthermore, we contend that ethical leadership acts as a critical contingency factor that reinforces the negative relationship between SRHRM and time theft through heightened moral awareness. Employing two-wave survey studies and a scenario-based experiment, our hypotheses were empirically supported. Our findings contribute to both theoretical and practical understandings within the domains of SRHRM and time theft research. Additionally, we discuss limitations and propose future research directions. (shrink)
