I was curious so I went to see what is there in terms of data and found: 1. "Firms and Layoffs: The Impact of Unionization on Involuntary Job Loss" - (2003 with data from 1997) https://ideas.repec.org/p/cen/wpaper/03-09.html https://ideas.repec.org/p/cen/wpaper/03-09.html > Results show that the impact of unionization is not significant except for (1) establishments that operate in the non-manufacturing sector; and (2) establishments operating in industries that have major collective bargaining agreements which contain moderate employment security provisions. Under those conditions, unionization decreases layoff rates; otherwise, unionization has no effect on layoff rates. Does anyone have anything more recent about this?
