%0 Report %A Braakmann, Nils %A Hirsch, Boris %T Unions as Insurance: Employer–Worker Risk Sharing and Workers' Outcomes during COVID-19 %D 2023 %8 2023 Jan %I Institute of Labor Economics (IZA) %C Bonn %7 IZA Discussion Paper %N 15893 %U https://www.iza.org/publications/dp15893 %X We investigate to what extent workplace unionisation protects workers from external shocks as predicted by models of implicit contracts. Using the COVID-19 pandemic as a plausibly exogenous shock hitting the whole economy, we compare workers who worked in unionised and non-unionised workplaces directly before the pandemic in a difference-in-differences framework. We find that unionised workers were substantially more like to remain working for their pre-COVID employer, at their pre-COVID workplace, in their pre-COVID job and to be in employment. This greater employment stability was not traded off against lower working hours or labour income. %K unions %K risk-sharing %K implicit contracts %K insurance effects %K COVID-19
