Unionization, compensation, and voice effects on quits and retention

This study explores the relationships among unionization, compensation practices, and employee attachment (quit rates and tenure) among trucking companies to assess the applicability of Freeman and Medoff's exit/voice argument. Unionization was associated with lower quit rates, higher tenure, a better compensation package, and stronger voice mechanisms. The relationship of unionization to quit rates and tenure becomes nonsignificant after accounting for compensation (pay and benefits), and voice mechanisms do not add explanatory variance.
