My onboarding was atrocious, my manager did the absolute minimum. Wouldn’t even allow me to shadow him for one day. On my second day he asked me what I had planned for work that day, he didn’t give me access to a crucial system for four months after I repeatedly asked him.
My mental health deteriorated after months of feeling like I’m sinking. Broke down at work (privately in a meeting room with just my manager) and told them I felt suicidal, I couldn’t sleep, my weight had plummeted, the stress was too much etc.
Their reaction was now to say I was a low performer (never said this before my breakdown) and they put me on a plan which meant I got no pay rise or bonus. It was announced on Friday that my manager has now got a big promotion.
Do I quietly quit or raise a grievance?
