DH was made redundant earlier this year from a job he loved. He has been very fortunate in current circumstances to find another job. He has been in it for 4 months now but seems desperately unhappy. He has always been very motivated I have never seen him so negative. He is normally a very positive person and I have rarely heard him say anything bad about his colleagues. However he does not like his new coworker. According to DH he has the habit of looking busy but not actually doing anything. He is apparently always making calls that's just seem like he is chatting, he books clients especially difficult ones on his days off so DH has to deal with them, when DH asks for information he often just answers he doesn't know, he goes to the shop on the pretence of buying something work related but is gone for a long time he was gone for two hours recent getting milk. When he came back he just said sorry I had to make a work call as well.
DH doesn't know what to do as he hasn't been there long and this colleague has been there for years and gets on well with mangement. He feels if he says anything it will just cause tension and won't look well.
He is obviously looking for another job and says he doesn't want to leave on bad terms.
Not sure what I'm really asking to be honest as I don't think DH can do much other than hopefully find another job. I just hate how down he is it is so out of character for him. My job is also at risk so I think he feels pressure that one of us at least has a safe job at the moment.
