DH employed a man to work for him at the end of October. This man seemed a bit odd, but his references checked out OK and he seemed a good enough worker, even though he has complained alot about the other members of staff not doing a good enough job (in his opinion). DH has already had words with him about this and explained that we work as a team, and bitching about the quality of other people's work is not constructive nor conducive to a happy workplace. Then, about 3 weeks ago, this man was kicked by a horse and took some time off. He went to DH and demanded to know why his accident wasn't in the accident book, he didn't think the way we operated was legal, blah blah. DH explained that the accident book he had been looking in was,, in fact, relating to the other business we share premises with, and his accident had been properly recorded in our own book (it had - I did it myself). Despite mumbling, he did return to work after a few days. Then, Landlord's wife caught him in my office, rummaging through drawers, filing cabinet etc. He didn't see her standing in corridor and she watched him for a while, before walking in and asking him what he was doing. He said he was looking for the Yellow Pages (in the filing cabinet?) but the alarm bells were ringing. Now, this afternoon, he has refused to come in to work, saying he worked too hard this morning, and the other man we employ in the same capacity doesn't do a good enough job. DH is at his wit's end, and doesn't know what to do about him - he seems for all the world that he is setting himself up to be dismissed and then try to take us to a tribunal - his actions have been too bizarre. Poor DH has only just set up in business 4 months ago and really doesn't need this. Any advice would be appreciated.
