A majority of postdoctoral workers at Columbia (NY) voted to unionize, the National Labor Relations Board announced earlier this afternoon. At polling places across campus over the past two days, postdoctoral workers and associate research scientists voted 729-339 in favor of joining the Columbia Postdoctoral Workers-United Auto Workers Union. The vote represents a significant win for the unionization effort, as CPW-UAW has become the first certified postdoctoral union at a private university.
