Store manager here, Tbh I'd do an HR exit ticket because tbh if your manager tells you that or tries to make you work, then that's a lawsuit lol. Goes against company policy, time off policy, workplace harassment policy. Manager should be fired immediately for that.

Tbh, just quit. Either in person, which given the condition you're in probably wouldn't be the best idea, I'd either do it through text (try not to message anything negative and be professional). If it is in person, oh have free range and say whatever you please.

Sorry that this happened to you. Hope for a speedy recovery. And hopefully you get a better job with way better management. Best of luck :)
