Anything where I've been stuck in one place or in an office doing clerical type work, there have been a few over the years in between other jobs.
Current job isn't great. Having to do too much finance stuff in it. I'm supposed to be doing statistical analyisis. Still stuck in an office but there are some hot women there). Plus I'm only working three days a week while studying.
Worst probably has to be the 4 months I spent as a trainee bank clerk in the 80's. Hated it. I'm very much a jeans and t-shirt person. I've been able to get away with that in every other job (even if it has taken a bit of work to adapt my employer to my way of thinking). The bank's attidudes were archaic. Plus they were trying to force me into selling products at the counter too. If an old person came in and they had loads of money in their accounts I had to send them down to an interview bay where someone would try and sell them stuff. I refused to do it. I used to go in wearing various t-shirts under a white shirt so they could be seen through the shirt. The Sex Pistols "Never Mind the B******s one upset them the most. It could be baking hot and if one person wanted to keepo their jacket on everyone had to, except I just ignored them. When I joined they said "new boy makes the tea". I just said "not any more".
Bizarrely, it's the only place I've ever worked where the manager actually praised me for being a stubborn, stroppy, argumentative and generally rebellious git. Apparently it meant I'd be good at dealing with difficult customers.
I had my first probationary appraisal with the manager after 3 months. I couldn't believe it was so glowing. He said "if you keep this up and take your banking exams you could be an assistant manager within two years". My reply was "that would be my worst nightmare, here's my resignation". What a relief that was to get out of there. Yep, that was definitely my most hated.
My problem hasn't been with jobs., it's generally the employer I have problems with. We're slowly heading back to the 1920's and 1930's and our current govrnment are helping make that happen. Wages and standards of living falling. All power slowly being shifted back to employers and employee rights eroded (like these latest Government proposals). I'm just waiting for dodgy Dave to re-introduce workhouses. There has to be a balance, yes employers need to be able to get rid of crap staff but to have no fault dismissals which mean that you can be fired because the company wants to bring somebody in on a cheaper wage or because you get a new manager and he doesn't like you. Then the right of appeal and availability to employment tribunals is being slowly reduced as well, meaning anyone unfairly dismissed is up poop creek without a paddle.
I have found though that if people genuinely believe you are a psychopath with mental issues they leave you alone. Especially when you let it be known that you keep a list of people who have seriously peed you off and that you wouldn't want to be on that list. I did once tell one of my bosses, who was a complete dick, that he could sack me if he wanted after we'd had a stand up row and I'd punched a hole in his office door. I then casually asked him what the company payout and pension is like for medical retirement. I did get a written warning lol.
I've only had to play that game at a couple of places I've worked though, as most of my employers have been reasonable and I am actually a good worker and do a good job I am.
I don't know why, but in most of my jobs I have been allowed to just get on with it without interference
