While I doubt this actually happened, I’m still disturbed by everyone cheering it on absent any context that would make OP not look like a petulant child.
Quitting without notice doesn’t require justification, fuck the bosses, whatever.
But for all we know, this manager had bent over backwards to stand up for their employees, or cover for them. Maybe this employee took advantage of that and was miserable to his coworkers. Those are just as likely as anything else, given that no further information was provided.
At least invent a backstory how this manager was dogshit or abusive, or the company was awful. Make us want to believe that you’re not just someone with a persecution complex who’s quick to anger and lash out.
I have a very nuanced take that involves licking boots nuancedly
Thank god you’re here, I was tossing and turning in bed at the thought that nobody was considering the feelings of the poor managers!
If they’ll fire us with no notice, we should quit with no notice.
