I have worked here 18 months.
I have not raised a grievance yet as I was waiting to see how this meeting went.
I have them in emails.
To put this in perspective - i am the oldest in the team and the oldest from who my manager has recently recruited. Not just by a couple of years but a significant amount of years.
He has also referred me as being a "mistress" to a work colleague and copied me into the email, which I find offensive.
In terms of the allegations he has only briefed what they are stating there are concerns and he has sought reports. However on 1 issue this has been going on for several months and I have documented evidence of my actions and behaviours (even though I am trying to think what these are). On the second issue I was the final person in the chain, took full advice from expert teams and decisions were made on this. However no one else has been asked to a meeting.
