I've handed in my notice at work because I'm not happy there, and my mental health is suffering. I had reached out to my manager for support but not much changed and I just think it's a poor fit. So I've handed in my notice and am job hunting. I told my manager I had another job lined up as they were trying to persuade me to extend my notice period beyond what's in my contract.
AIBU to lie and say I have another job lined up to avoid any awkward conversations? I'm not close to any of my colleagues and don't have LinkedIn etc so they wouldn't know. If they did find out I would just say the job fell through.
