I'm thinking of keying my shitty boss's car
What did your boss do to make you want to key their car?
Because he's such a shitty boss.
Bad bosses make life miserable, but damaging his car won't help. It will only get you in more trouble. You should just quit and find a new job.
I'm just thinking about it and I'm still trying to find a way to get me out of this shitty job.
I do not think that keying his car is going to get you out of your job. However, if it does get you fired than you probably have a bigger problem on your hands. Either way, if you truly do not like where you work, you are better off quitting instead of doing something that gets you fired.
