This study (a) compared the effect of perceived supervisor support (PSS) and perceived coworker support (PCS) on work attitudes; (b) examined the moderating role of gender, tenure, and job type in the support—attitude relationship; and (c) tested a theoretical model hypothesizing relationships among PCS, PSS, perceived organizational support, and work attitudes. In a meta-analysis, PSS was found to be more strongly related to job satisfaction (.52 vs. .37), affective commitment (.48 vs. .28), and turnover intention (—.36 vs. —.19) than was PCS. Further, job type (customer-contact vs. non-customer-contact jobs) was found to be a significant moderator. Finally, the proposed model received empirical support. Different forms of support were closely related to work attitudes and to each other. Implications for research on social support are discussed.
