I've been in two (maybe 3) unions. Postdocs unionized and made it so that very-short-term postdoc contracts weren't allowed. After I got my PhD my advisor wanted to pay me as a postdoc for the 2 months before my postdoc at another university began -- this would have been EXCELLENT for me. But, union rules, he wasn't allowed to do this. So I had to float my own way for a couple months. Thanks United Auto Workers (the people who ran the postdoc union).
