Despite achieving substantial contract gains, including significant wage increases, the 2023 pattern agreement reached between Unifor—Canada’s largest private sector union—and Detroit Three automakers was met with mixed reactions from union members, with particularly low support from skilled trades and more senior members. This study reveals how intra-union dynamics were shaped by shifting socioeconomic conditions, comparisons with the United Auto Workers, differences between production and skilled trades members, generational tensions, and leadership conflicts intertwined with strike dynamics. These factors influenced bargaining expectations and union strategy. The findings suggest that intra-union tensions weakened member solidarity and support for the historically strong pattern agreement, highlighting the complex interplay between external pressures and internal union dynamics in collective bargaining.
