After reading comments here I thought after reading this I would largely agree. It's true that sarcastic tickets don't help but they're not a fireable offense.

After reading comments here I thought after reading this I would largely agree. It's true that sarcastic tickets don't help but they're not a fireable offense. It should be noted that this is one person's account of what happened. It's not clear to me where this contractor was. Sweden? Even as a contractor, knowing what I do about how large companies work, a manager can't typically just fire somebody. There is an HR process that needs to be followed. For people saying he should leave and/or put his head down and do his work, that seems to be part of the problem: the constant interruptions. I've had this situation before. In some cases I've had some success with "you've just asked me to do Y when I'm doing X. What do you want me to do: X or Y?" For decent to good managers they understand this is a prioritization issue. But for other managers this is viewed as insubordination. Managers have to be held to a higher standard by the company because a bad manager can do an awful lot of damage to the career of their reports. Unjustifiably low ratings, subpar ratings that may make team transfers impossible, even PIPs for really no good reason. Companies should be hypersensitive to bad managers but so often they just aren't. Bad managers will shift blame for their own failings and it can be extremely hard not to be collateral damage before you realize what's going on. As for Spotify not hiring this person back, that's just standard HR policy BS. There's probably not much you can do about that.
