I'm going to tell a cleaner to clean more space than I hired her to do.
You can't be real about this. Why would you want her to do more?
I want her to get fired because she was rude on the phone.
If you want to end the working relationship, you should just let her go instead of creating problems and asking someone to do more work than you are paying them for. You shouldn't take advantage of people that you hire, and you shouldn't be passive-aggressive to try to get her in trouble.
I don't care. I just want to make things difficult for her.
But didn't you want her fired? Don't you think it's unfair for her to have a hard time from your demands? I still believe that you still should just fire her up front to avoid drama.
