My boss is a nightmare and has got worse recently. She sits playing computer games all day and does virtually no work. We share a large office with the rest of the team, which consists of the two of us, five men and the secretary. Three of the men are pretty strong characters and frequently argue with her and shout her down during meetings. Instead of standing her ground, she seems to fold and give in to them all the time. I think the men would respect her more if she was a little more assertive, and be less "difficult". One of them told me the other day that they were plotting to completely undermine her (which, to be frank, I don't think would be that difficult) and try to get her to either resign or go on long term sick leave through stress (I think the latter is a strong possibility).
Now I don't like her as she has made life really difficult for me on several occasions, but I don't agree with the behaviour of the men either, which I think is bullying and picking on a weaker character. But should I tell her, or maybe her boss what is going on?
