Job cuts, job guarantees and unions

Using unique nationally representative workplace data this paper shows that unionization increased the probability of within-workplace job cuts and the incidence of job security guarantees. As theory predicts, both are more prevalent among market-sector workplaces with higher union density and multi-unionism. In the public sector, levels of unionization affect only job security guarantees, not job cuts. Explanations are developed in terms of union bargaining power and union voice services.
