--- - |2 Abstract We examined socioemotional microfoundations of perceived corporate social responsibility (CSR) and posited that employees’ perceived CSR triggers a perception‐emotion‐attitude‐behavior sequence. Drawing from appraisal theory of emotion, we hypothesized that perceived CSR relates to emotions (i.e., organizational pride), which relate to job attitudes (i.e., organizational embeddedness) that in turn relate to job behaviors (i.e., decreased turnover). To test this model, we conducted a multistudy investigation involving different samples, designs, and data‐analytic methods. In Study 1, we conducted an experiment and found that participants who envisioned working in a firm that was active regarding CSR activities reported greater pride and organizational embeddedness. We then conducted two field studies using a nonmanagerial sample (Study 2) and a managerial sample (Study 3) and found that participants’ perceived CSR was positively related to their pride, which in turn was related to stronger organizational embeddedness. Stronger organizational embeddedness was related to lower turnover 6 months later in Study 2 but not in Study 3. In Study 4, we conducted a longitudinal four‐wave 14‐month study to test the proposed relationships from a within‐person conceptualization, and the results were also supportive. Thus, the proposed perception‐emotion‐attitude‐behavior framework received broad support and illustrated that stronger microfoundations of CSR research could be constructed through understanding employees’ emotional, attitudinal, and behavioral reactions to their perceptions of their employers’ CSR. - Personnel Psychology, EarlyView.
