I'm wondering if maybe the problem is with me so please be gentle.
In my last job, upon resigning, I raised a grievance as I wanted it know that I had felt forced to resign. My grievance was not upheld due to insufficient evidence but I do know a huge rework came into our department because they did find issues and enough to support other parts I'd raised. In summary, there was a huge lack of diversity, I was the only non-white female (only 3 women out of 100 total) and only non-privately educated and was told I don't belong. A higher up colleague also made a comment about my race not fitting in (my first real experience of racism because I am so British I rarely notice I'm different and I am just about olive-skinned)
So, I wanted to leave my current job due to the culture. It is far worse than the previous place. Not racist as far as I've experienced, but hugely toxic, gossipy, lots of blaming etc. In my department there are 30 people. I joined 13 months ago and 10 have left. I am currently the only person left in my sub-division and all the leavers blamed toxic management but did not make the official reports in exit interview. Now, there are two people at the centre of my reasons for leaving. Mostly one woman who did not like that I once made her look bad (not my intention and was entirely her fault) and since has had a vendetta against me. To my face she will say my work is great etc. then behind my back attempt to block promotions etc. Luckily, I have evidence of it all and her behaviour.
When I resigned, the head of the UK part of the firm (NYSE company) was devastated as I have quite a big role. He offered me lots of different things to stay but I have a new job (they don't know) that will be tough but is a huge payrise with amazing benefits. I cried (tried not to...) explaining the reasons I decided to leave. He immediately called HR to speak to me and HR requested I put in a formal grievance, noting that they agree there is problems and my experience has been awful.
My question is - would you? Am I just too sensitive?
