The relationship between organizational citizenship behavior (OCB) and two organizational rewards—salary and promotion—was examined. Employee gender also was tested as a moderator. Data from 440 individuals employed in multiple settings indicated that individuals who reported engaging more frequently in OCB directed toward the organization (OCBO) also reported receiving more promotions. Further, results indicated that gender was a moderator such that the relationship between OCBO and promotion was stronger for males than for females. The results also revealed an interaction between OCB directed toward individuals (OCBI) and OCBO. Specifically, high OCBI and low OCBO related to lower promotion rates than did low OCBI and low OCBO. Results are discussed in terms of implications for individual career development.
