Indiana University-Purdue University Indianapolis (IUPUI) / Despite its status as a commonly used and seemingly vital talent management system, performance management has received an abundance of criticism surrounding its effectiveness and utility in organizations. Existing deficiencies in performance management are largely attributed to gaps in its strategy and implementation, with researchers arguing that organizations need to spend more effort supporting personnel engagement in informal, “everyday” performance management behaviors to drive performance. The present study sought to expand on existing performance management research by investigating: 1) how supervisor engagement in informal performance management behaviors influences employee perceptions of overall performance management and 2) how employee feedback orientation and implicit person theory potentially alter those perceptions. The hypothesized model was tested using an online survey sent through Prolific academic to a random sample of 351 full-time United States employees. A series of hierarchical regressions revealed that employee perceptions of performance management were positively predicted by supervisor engagement in informal performance management behaviors. However, employee feedback orientation and implicit person theory were not found to significantly moderate these effects. The present study contributes to performance management literature by examining the degree to which informal supervisor performance management behaviors shape employee reactions to performance management. Implications, limitations, and directions for future research are discussed.
