Brief background, worked for the company 15 years with an exemplary record. I was diagnosed with adhd 2 years ago and i had reasonable adjustments put in place regarding how much work i am expected to complete (basically less than my peers - no specific target was set), and also around ensuring communication is open and that I'm given notice of changes etc in advance wherever possible to assist me with managing change. This has worked well since although i do have to regularly remind them that they're reasonable adjustments and not favours. I'm more than likely also autistic but i haven't got diagnosed with that as waiting lists are 7 years.
I have had an incredibly stressful time outside work recently, and i have managed to keep it from affecting work except that in January my performance slipped in terms of how much system based work i completed, compared to my previous months.
This is not a measure that i have ever been given a specific target on. I've always just been advised it's something the managers keep an eye on to see if any support is needed. During January there wasn't much system work to do, so my line manager encouraged me to finish up any non system based projects i had on the go. None of that work would have shown up on that score.
Was informed in Feb by my line manager that i hadnt completed enough system based work in jan, and that my score was considerably worse than it had been in previous months. i immediately came up with a plan to improve that score, which i implemented and it did improve back to its pre January levels straight away in Feb. She knew that my mental health was fragile, i asked her to just trust me to sort it out and not put too much pressure on. I did sort it out straight away.
I was then invited in for what i thought was an informal chat with my manager last week only to be absolutely blindsided by an in depth, minute by minute investigation of every day i had worked in January with every system based task i had done, and i was asked to account on the spot, for gaps where no system work has been done for half a day or so. (I was probably doing non system project work - i havent had a chance to look at this yet as I've been off sick with mental health since). Apparently it had been discussed in a senior manager's meeting about how bad it was.
As i have adhd i can't remember what i had for breakfast yesterday, let alone what i was doing on a specific day 2 months prior. I was all over the place trying to work out what to tell her all the while she was jumping between days and spreadsheets trying to get me to commit to saying what i was doing so i was completely confused. I haven't really got a clear memory of what she would have taken away from the meeting.
It wasn't until half way through the meeting that i asked, because it was feeling very unexpectedly formal, and she confirmed, that this was an investigation and the decision was with senior managers to decide if they would be taking me down disciplinary route or not after she took my answers back to them after this. Afterwards she sent me a calendar invite for the meeting we had just had, entitled "investigation meeting". If i had accepted that, it would have then made me look as if i knew it was an investigation beforehand when i had no idea, so i left it unread.
Whoever decided to do an investigation, I don't feel that they would have considered any of my reasonable adjustments. They certainly didn't consider the ones that said i should be communicated with in an open and honest manner because i didn't know it was an investigation.
I also think if they've compared my performance to that of my peers, which was alluded to by my manager that my score looked very bad next to them, then they haven't taken into account my adjustments in that respect either. This is a score that has never had an agreed target attached to it. I think they were looking to see if I've been sitting around getting paid for doing nothing but if they had asked me i would have explained it all no problem - because of my adhd, i work differently to other people but i get the results and it's never been raised as a problem in 15 years.
There's also a potential GDPR breach as i believe there would have been at least one person in the managers meeting who didn't know about my disability, and who potentially does know now.
If they'd told me i was being formally investigated over one bad month, at least it wouldn't have been such a shock. As it is i was barely keeping my mental health together and that pushed me over the edge. I thought i was going in for a friendly check in with my team leader who i previously had an excellent working relationship with.
I feel that they've been really heavy handed and i wonder if they're trying to manage me out based on this one poor month. I also think I've possibly been discriminated against on the basis of my diagnosed disability.
Question is what do i do now? Unfortunately i wasn't in a union - i had been but i cancelled. I have now rejoined but it's a bit late to get help for this.
