There’s talk on the radio about whether should you join a union as things get hard — collective representation being a comfort when jobs are at risk. In the seventies I was a union convener for NATKE. Under the threat of job losses we walked out and managed to negotiate better pay and conditions.
A year or so ago I joined Tssa when I knew my employer wanted me out. Despite a just cause, there was little help; so if you consider joining a union — make sure it has teeth.
