"Much of the gender pay gap is generated within workplaces, making it paramount to understand which workplace policies effectively address gaps. Our article asks when policies limit gender pay gaps across employee tenure to identify potential temporal weak points. We analyze a representative panel of 10,000 establishments with over 850,000 employees using the 2005–19 waves of German-linked employer–employee data (LIAB). Two key findings emerge. First, a temporal perspective on workplace policies reveals that no policy under study—formalization, identity-based career programs, and child care assistance—reduces gender pay gaps at hire. Instead, policies only address additional disparities that accumulate after hire. Second, only identity-based career programs narrow gender disparities for all women. In contrast, seemingly gender-neutral formalization is insufficient, while providing employer-sponsored child care has mixed effects depending on employees' education. We conclude by discussing the implications of these findings for organizational policy and future research."
