I think the worst I ever got caught for was an eternal saturday at work where almost everyone called in sick, was me, and the assistant manager from hell, and one other guy who was really cool and therefore made it sort of bearable. I ought to state, if you've seen ' Office space ' the manager in that was a clone of mine, even down to doing the whole 'ummm...yeah..we're gonna need to stay behind' crap.
I'll abbreviate the assistant manager down to ass man I think, or just ass, saves time, anyway, this is a music and movie store, its a saturday weeks from xmas, and not only is he taking one of us off the till regular, to 'tidy up' while there's queues of 40 - 50 people out the door, he's doing absolutely zero to support us, because he's doing his obsessive tidying up, telling customers to come and see one of us, when they approach him.
On top of that, he tells us 'we can't do lunch breaks today guys, not enough staff', at which point we flatly told him we ARE or we're off home now. Anyway, we somehow make it to closing, and my stress is at bursting point, genuinely, and I'm slowly thudding my head against a wall repeating 'please make him stop, make him go away, make him stop' etc, I think my mind temporarily snapped. I look and he's there just staring at me, and then sees I'm looking at him and walks off downstairs.
Anyway, I'm in the next morning, and the area manager is in, turns out he's there to give me a warning for 'affecting team morale'. Amazingly I didn't get fired for using the words 'clueless fuckwit' in an official disciplinary interview when discussing the ass man.
turns out it got overturned when I told the others and at least three members of staff went upstairs to back me up on being a good, helpful member of staff pushed to the edge by someone utterly pointless.
I don't know if a visible mental breakdown in front of your boss counts as rebellion, but he did move on soon after.
EDIT: oh , and in another store job, where I was left alone to run the place and dumped on 14 hours shifts, there were a few occasions where the 'back in 15 mins' sign would go up, the store would close and unholy acts would occur in the bathroom, I'm not proud of it, but is it truly wrong to be thinking 'yesss, I'm getting PAID for this!'? Apologies for too much info, but its more of a rebellion tale than the other bit of mine, thinking back.
In my defence I was young, male, and 14 hour shifts with no breaks?
