So, this happened a few days ago, I'm currently waiting for my manager to sit with me and go through my grievance (they work under my Director).

I work as a Regional HR Advisor and I covered another colleges area (so the entire South Region) from March until around June this year. In those few months, I successfully did the work that my previous colleague (who had tons more experience than me) failed to achieve in almost 2 years. I did this while also supporting my own region (consisting of 9 Area Managers, who have roughly 14 managers each). 

I only got promoted from Administrator to Advisor 1 year ago.

I do suffer from BPD (Borderline personality disorder), Depression and Anxiety. I am medicated and am nornally highly functional due to the hard work I have put in to keep it all in check over the past few years. 

Now, I need some help putting this whole thing into perspective, the grievance i put is that i feel they want to get me out the business due to my mental health and that I am very outspoken about my rights. 

A bit of backstory, they previously tried to capability manage me out of the business due to my mental health, I even have evidence for this. I regret not putting in a formal grievance then but hey ho, I was in a shit place and wasn't thinking great. 

I have decided that I will probably have no choice but to leave and find a new job at some point, which is a shame as I get nothing but good feedback from people, not directly all the time but even my other colleagues get told about my work by other managers. So I know I'm doing a good fucking job.

Out of everyone, I know I work the hardest, I'm the easiest to get a hold of and again, even my manager has admitted they hear my name around a lot and always in a good way.

Am I overreacting here? Am I being unreasonable with my grievance? I did it formally so I don't regret it again and so they can't ignore me but am i being too harsh?

I just feel like they are using this as a way to make me want to leave as I have openly stated that if they continued to ignore my hard work and not reward it I would most likely leave.

Also the thing that pisses me off is that they were happy to try to get me out the business for 'poor performance' resulting from my mental health problems but when I'm doing awesome work they don't want to reward it. I probably have missed out a few bits but this post is long enough.

So yeah, some perspective would be much appreciated!
