So I work at a tennis club part time as a receptionist. They expect you to be constantly working even when it’s not busy and for not enough pay. Therefore, I have been kind of intentionally doing a shit job and they have noticed. I received an email saying that I will no longer be working the front desk. They are instead having me clean off courts and string tennis rackets. I don’t wanna do that lol. How do I tell them no fairly nicely in an email?
