I’m also a supervisor at work but I don’t always get to decide on things. Often senior management gets an idea in their head and then I have to figure out how to implement it without breaking everything.
I do get to say I’m against something and I told you so. Which is usually followed by a compromise solution.
Some assholes hang around with other assholes because 1) it validates them, 2) it gives them someone to argue with,3) they have no one else because normal people cut them out of their lives
