NC'd for obvious reasons but could do with some advice, esp from anyone with some HR experience. Sorry it's so long, wouldnd't normally write this much but I'm really struggling.
I work for a learning disability charity. I recently employed someone with a related learning disability who interviewed well and seemed like they would be a good fit. The OH report outlined the features of this medical diagnosis and said all they'd need was a little extra time/support. Fair enough and thrilled to get someone who could represent us and this learning disability.
It's been 7 weeks but from the first few days it's become glaringingly obvious that they had minimised the challenges they have whether this was intentional or not. They don't meet some of the essential criteria from the job description and had overplayed their experience in this field and the impact of this is that they have made mistakes which have been inconvenient/slightly damaging such as overwriting files, misunderstanding tasks (despite me putting in reasonable adjustments to ensure they can do it to the best of their ability), being careless more than once despite me asking them to be careful which haved caused problems with our service users and offending one of our key clients due to how they were in a meeting with them. I've put in a whole raft of reasonable adjustments but the improvement is marginal and I don't think will change given their diagnosis. It has taken up an inordinate amount of my time where I have been unable to progress larger client relationships as I've needed to take over work that this person has - to be frank - messed up. I've tried, I really have, I want it to work for this person as one day this could be my own daughter.
I've needed to feed back the things that have caused issues and this person has taken it badly. They emailed me on a Sunday saying that I'm obviously a "nice person and mean well" but my feedback is coming across as critical and negative, that I need to give them more positive feedback (I've tried but it's slim pickings) and their mental health is suffering. They also keep mentioning their disability on a regular basis which feels a little pointed given we're a learning disability charity.
They're also part of a particular cultural community which they have mentioned a couple of times in order to say that a) they've got many influential contacts one of whom is our major supporter and b) if anyone has any trouble there is always someone who will pop up to help. They feel like veiled threats to me though I admit I'm feeling depleted after the last 7 weeks. Their performance keeps negatively impacting our business goals but as they are disabled we need to ensure we support them. Plus the reputational risk if they decide to use their influential contacts against our charity.
HR have been helpful but my gut instinct is screaming that this person being in this role won't work. They obviously have skills but they're not right for this role. They have a 'buddy' and all the reasonable adjustments they want have been put in place. I'm now exploring the route of another OH referral and the Access to Work scheme.
I'd really appreciate some advice on how to tackle this if anyone would be generous enough to help.
