That previous job I mentioned, just before I left one of the managers had literally every single other manager file a complaint against him. The management in that company were very clique-y and if you weren't part of the in group you were fucked. A few years previously a friend of mine went for a supervisor job and lost out to one of the manager's friends. That guy left a few months later to become head of marketing for Costa Coffee all across Ireland. The person they gave the promotion to had like a certificate in textiles, less experience and was demonstratively shit at her job. Anyway, the original manager I mentioned had gone to HR about a whole bunch of really inappropriate shit that was going on, including management's total mishandling of a sexual harassment complaint and then suddenly he was being called in to the office because weirdly every manager had written very similar complaints against him. Once his union got involved the whole thing was dropped because they realised they were heading down the road of getting sued because their vindictiveness was only matched by their stupidity.
