This piece is mostly a response to how people here thought the author was too paranoid about being honest in an exit interview. And the answer is unionization?

I 100% agree you should be a mercenary at work. Look out for number 1, HR isn't your friend, etc. But being so paranoid you can't even speak your mind in a nearly zero stakes situation of talking to your company before you leave speaks to a very negative outlook on work that seems honestly exhausting.

And more to point, if you are a good mercenary, unionization only harms you.
