Long story but the jist is we have a twat at work who is just one of those pain in the arse and likes to shit stir. He's disruptive, has caused a near punch up amongst 2 other colleagues and spreads poison. We work in a factory and what he does is specialised so not easy to replace, not impossible, but not easy.
He has repeatedly made complaints to hr about our boss but then retracts them the next day. He says he's being bullied but he's not, he's just being asked to do his job.
This has been on going for a couple of years now, hr don't seem to bother with telling him he can't keep doing this.
My question is is there something official that can actually turn the tables on him and for him to be investigated to ensure that he can't keep doing this. I've tried Google but I can't seem to find much so I thought I try here
Thanks
