Using this policy-induced variation in the cost of repaying debt as an instrument, we find that higher household debt significantly lowers the likelihood of unionized employment, with the effect concentrated in states with right-to-work (RTW) laws. We interpret this result through the lens of institutional labour market frictions. In states with right-to-work laws where agreements requiring all workers to join the union or pay union dues are prohibited, financially constrained workers avoid unionising since this might involve higher conflict, instability, or employer pushback. The findings connect household financial vulnerability to collective-bargaining institutions, highlighting how personal balance sheets and legal regimes jointly shape labour-market behaviour.
