I'm on sick leave due to my mental health. I'm due to go back to work next week but I'm not ready to go back and don't think I'll ever be ready to go back. I'd rather have a fresh start somewhere else.
I need to hand in my notice, but I have no idea how to do it. Do I message my line manager informally on Teams to let them know I'm handing in my notice and then follow it with the formal email?
My notice period is 2 months, do I mention that in the resignation email or see what they say? What can I expect to happen when I hand in my notice?
