Abstract
Corporate social responsibility (CSR) and irresponsibility (CSI) can influence employee voice behavior in online review platforms. This study utilizes online employee review (OER), builds upon ethical climate theory, and hypothesizes the independent and joint effects of CSR and CSI on two aspects of employee voice – OER volume and OER valence. Using novel OER data of US tourism and hospitality firms, we perform a panel data regression with industry and year fixed effects. The results indicate that firm CSR engagement increases both the volume and valence of OER, whereas CSI accelerates (attenuates) the positive CSR effect on OER volume (valence). These findings can help tourism and hospitality firms implement CSR strategies for enhancing employees’ word of mouth from both volume and valence perspectives.
