OP here: I want to thank you all for your advice. DH says we will see what his work does and how they handle his pay. We are getting his paycheck, but from his vacation bank. That will only last so long and WC apparently did pay him, but nobody knows where the checks are because his work does not communicate well at all. If the checks do arrive, we will have to see what they do: either we keep them or they put them back into his vacation bank, but his payroll lady does not know how to do that. They also said it maybe a case where any vacation time he earns, will go to repaying what was used and he just keep the checks. She said that may be easier for her to do.
We are just worried because dislocated knees are known to be lifelong issues and did not know how to handle that if he cannot do his job. As of now, they are allowing light duty because somebody quit, but prior to this they told him he could not come back until he was completely proficient again. So he is really worried that they will try to get rid of him or tell him that unless he can do the job to the job description, he is gone. He is union, so if that does happen, he will be contacting them. They have been really bad to other employees who have been sick or injured before (not work related). They have terminated a lot of people due to issues as stated. They are really horrible to work for in terms of caring for their employees or trying to help them in different situations. Since he is a pension employee and there are only 4 of them left there, they have said repeatedly that they want them gone.
If they are nasty and do not get things taken care of,we will contact a WC attorney. Hopefully get it settled or something. Thanks again.
