Not union related but just an apropos ... Our company had a whiteboard where people could write things to improve the workplace. Some people said more compliments! but eventually serious stuff like a decent health plan and pay raises got on there.
Management saw this and held a meeting where they hired this guy that climbed Mount Everest to motivate us and eventually told us to look inward when there's problems. I was like, wtf is this shit? But it did work on a few people. They were all, "yeah, I should think about what I could do ..."
Immediately started applying for jobs after that shit.
