Hi, I'm after a bit of advice. I've been in the same company for years but last year I moved to a different department. I fell pregnant and notified my manager a month into my new job. Despite being fully qualified for enhanced mat leave and pay, my boss couldn't accept my request to take the year off and told me I'd need to find the cover myself. In the end, to avoid him having to find cover, he suggested I take a couple of months and return to WFH. After some thought, I agreed to the terms because I was worried about returning to a hostile environment or not returning to a job - my skill sector is niche and jobs are hard to come by. There was a critical deadline on the project so I assumed it'd be temporary and I can resume leave afterwards. I was contacted to work several during my mat leave - agreeing to because I felt obliged to. When I returned I mainly worked from home but also began going in to work more frequently to meet the project deadline and working out of hours. After this I tried to request a month of shared parental leave to recover and spend time with my child before starting nursery but it was denied. I got offered a job at another department and accepted. Since handing in my notice, my manager has not spoken to me not even to acknowledge the notice. It's been a month. I'm at a loss as to what to do going forward as I feel used and unappreciated. Do I raise a grievance or count my losses and leave?
