I am planning on quitting my job due to health reasons and it's not viable for me to give 2 weeks notice, my workplace has also treated me poorly due to my ongoing health issues and treated me even worse when I couldn't come in because I had covid. So the relationship isn't that great between me and my manager anyway. But I want to know what a polite way of resigning without the 2 weeks notice would be. Can I still give them a resignation letter with no 2 weeks? And what should I say in it to make it as polite as I can. Thanks in advance
