As a team lead and manager, I've had SWE friends mention that management shouldn't even exist. Petty arguments, performance issues, termination, even sexual harassment reporting are things I've had to personally deal with.

Well that shouldn't be an issue in a professional workplace and functioning team, is the rationalization. I couldn't agree more! Yet, there's a huge gap between what should and does happen when a bunch of humans (sadly, mostly men) work together.
