Bit of a weird one. My old contract said 1 month notice. I got promoted to a more senior role. The variation of contract should have said my notice period would be 3 months. But it said nothing - so my existing one month notice period stands.
Handed in my notice and manager thought I had 3 months. HR confirmed it’s 1 month but manager had asked if I would work 3 months notice because they will struggle to find my replacement.
AIBU to refuse? I feel bad but I shouldn’t
