Researchers are employed on casualised temporary contracts in some universities, which force them to relocate around every three years when funding streams change, typically to another country. Historically this was done just one for a "postdoc" research project, but modern funding now devotes far more money to contract research than teaching posts, and so most researchers now face a whole career of living in this way. This often leads to the breakup of their families and friends and sometimes to mental health problems.
