Postdoctoral researcher unionization is the formation of labor unions by postdoctoral researchers (postdocs). It has been driven by increasing competition for scarce tenure-track faculty positions, leading to more people residing in postdoctoral positions for a longer time. Unions often challenge the low pay, minimal benefits, and lack of job security that are typical of postdoctoral positions. Unionizing is however sometimes seen as creating a culture clash of tension between postdocs and their academic advisors, and some question the suitability of a union for a temporary position. Some universities seek to avoid pushes for unionization by proactively addressing the concerns of postdoctoral researchers.
