Social exchange theory suggests that employees feel commitment toward both their employing organizations and their work teams, while also experiencing varying levels of support from these same entities. Unfortunately, previous work has neither fully explored this possibility nor tested the capacity of currently available instruments to adequately measure the distinctiveness of the associated constructs. To address this need, we collected data from 902 employees in four diverse organizations. As predicted, respondents distinguished among organizational commitment, team commitment, organizational support, and team support. Furthermore, as predicted, perceived support from an entity predicted commitment to that same entity.
