I worked in the public sector for a while and had a 6 month review, they said I was adapting to the role very well, showing great promise, quick learner etc..
The manager conducting the review put in the room for improvement section that I should consider wearing a tie. I said I wasn't going to, it wasn't in the job requirements when I was hired and I don't even own a tie.
Next day turned up to work and there was a tie sitting on my desk, handed in my notice about a week after that. Perhaps petty on my behalf but the place was packed to the brim with utter workshy weirdo control freaks.
