Viewing organizational citizenship behavior (OCB) engagement from the time cost perspective, this study not only investigates the direct effect of person—organization (P—O) fit on OCB but also examines the moderating effect of time evaluation on the effective magnitude of P—O fit on OCB. Specifically, I hypothesized that the positive relationship between P—O fit and OCB will be strengthened (weakened) if employees have a higher future (present) orientation time perspective. A sample of 262 bank financial specialists with supervisor-rated dependent variables is used to examine the hypothesized relationships. Research findings suggest that P—O fit can predict OCB engagement. I also found that time evaluation plays a moderating role in the relationship between P—O fit and OCB such that P—O fit will have a weaker predictive power if the employees have a higher present-orientation time perspective. The research results provide further understanding of why employees engage in OCB.
