Using a novel methodological approach, we combine thestochastic frontier technique with an Oaxaca-Blinder-type decomposition to separate sick leave into medicallyjustified and "opportunistic" days. Our analysis, based on detailed administrative data of workplace accidents inSpain, reveals that men and women recover at different rates for the same injuries, with biological differencesexplaining the majority of the observed gender gap. Additionally, we identify that men tend to use more sickleave days for reasons unrelated to health recovery. The findings offer valuable insights for policymakers andemployers, providing an empirical foundation for targeted policies that reduce gender-based discrimination inthe workplace and ensure fairer resource allocation. This research contributes to a deeper understanding of thegender gap in occupational health and offers implications for improving workplace equality.
