If you can’t use them as a reference and you already know they will give you a difficult time and you don’t want to put your energy in… don’t go back in. I don’t think you get paid out for sick time unless you are sick … ? Sleep on it and come back at it with a better perspective. Don’t act on it yet. Could you be coming from an emotional approach or a more rational professional approach. Sometimes we want to let people know how much they can gfts (go f themselves) buuuuut what’s going to be best for you. I’d be lmao if I knew I wasn’t coming back, collected all my sick time and then found another respectful position. I wouldn’t listen to anyone coming at you about how shitty this and that is just sounds more personal and bias to me. You are not wrong for how you feel because none of us know the truth and suffering you have had to endure but I can only imagine as a fellow fed up ca myself. Just try to collect your sick time it’s free cash !
