Hiring Temps but Losing Perms? Temporary Worker Inflows and Voluntary Turnover of Permanent Employees
研究西班牙企业雇佣临时工对正式员工自愿离职的影响，发现临时工流入会恶化正式工工作条件，导致其主动离职，尤其在非制造业和低技能岗位更明显。
This article investigates the effect of hiring temporary workers on the voluntary turnover of permanent employees. It argues that inflows of temporary workers erode the working conditions of permanent employees, prompting their voluntary departure. Using a unique panel dataset of individual-level monthly payroll data over an eight-year period in a sample of Spanish companies, a positive association between temporary worker inflows and the voluntary turnover of permanent workers is found. The results are robust to diverse specifications and are strongest for firms in non-manufacturing sectors and for firms that hire proportionally more low-skilled workers, contexts where the hiring of temporary workers may be more disruptive for permanent employees. Since the hiring of temporary workers is unlikely to threaten the employment of permanent employees in the dual labour market of Spain, the results indicate serious disruption costs associated with temporary hiring in organisations.
