PurposeFrom a social cognitive perspective, the current study examines how the relationship between the employee and the organization changes following supervisor motive misattribution of organizational citizenship behavior (OCB).Design/methodology/approachThe current study utilizes an experimental vignette methodology (EVM), linear regression and Hayes' (2017) Process Version 4 macro in SPSS to examine the relationships between supervisor misattribution of employee OCB, personality and individual differences and future organizational citizenship behavior intentions.FindingsResults indicate that supervisor misattribution of employee OCB, specifically when the act is attributed to impression management, will reduce the intention to engage in future OCBs. Results also indicate that this negative relationship is enhanced when subordinates are high in openness.Research limitations/implicationsThis study extends social exchange theory by demonstrating how the misattribution of motivation to perform OCBs creates a negative social exchange and discourages future organizational citizenship behavior from the employee. The current research demonstrates the importance of supervisors understanding employees' motivations for engaging in (OCB). If an employee engages in OCB based on intrinsic motivation, such as a desire to help others, and their motivation is attributed to external motivation, such as impression management, the employee may feel misunderstood and believe their values and motivations are incorrectly perceived, leading to reduced OCB.Originality/valueThe current research is examined using EVM. By immersing participants in realistic hypothetical scenarios, experimental vignette methodology allows researchers to explore the intricacies of decision-making across unique scenarios, unraveling both the “why” and the “what next” behind decision-making.
