Organizational restructuring involving mass layoffs is an integral part of the corporate strategic landscape. While aimed at increasing a company’s efficiency and profitability, it often falls short of desired objectives, partly due to negative consequences for remaining employees, the so-called “survivors”. As workforce reductions may jeopardize a company’s legitimacy, we develop a model that links the change in post-restructuring employee productivity to the factors that help mitigate legitimacy issues. By using a comprehensive and innovative dataset of restructuring announcements reported by (...) European companies over the post-crisis period, we analyze the moderating effect of the restructuring extent on the role of corporate social responsibility (CSR) and economic justification as legitimacy tools in counterbalancing the negative effects of job reduction measures. Our findings reveal that in reactive layoffs, induced by financial difficulties, initially high levels of CSR help lessen negative effects of restructuring on employee productivity in low-extent restructuring events; while in high-extent restructuring events employee productivity is supported by continuing investments in CSR. We provide evidence that both the level and dynamics of CSR practices play a significant role, and their effect on employee performance is conditional on the restructuring context. (shrink)
