A famous quote goes, “Money corrupts, but power corrupts the most”, and it makes so much sense when you look at the atrocious behavior of toxic bosses. Once upon a time, they were novices, too, but when power gets to their head, there’s no going back, is there?
Just look at the original poster’s (OP) boss who somehow assumed that our guy was fired and sent him an extremely foul message, full of abuse. Stumped by the whole situation, he approached HR, but they were no help either, probably leaving him more confused than ever!
