Do not quit !!!! - He needs to keep a log of when he has called and who he talked to, time and date... Has he called the HR director??
I would seek legal council right away.!!!
They are using him for his license, make sure that he calls whoever the liscence is issued through, and can he be held responsible for anything that they might do? That could cause him to lose his license for the furture.
You can draw unemployment if you state that you left due to a hostile work eniviroment. If he does quit, make sure when he wrights his resignation that he is leaving due to hostile work eniviroment, and that he has tried to call and trying to come back to work, but is not getting any where. Also that they are holding him hostage by not giving him any information and this is causing a hardship on him and his family. Make sure to include that he has not abandoned his job!! Get a copy of the paper or if his job is lisited internal see if you can access it. or possibly maybe someone would be willing to help him get a copy, he does have a right to it as he is not been terminated and is still and employee. include information about them using his license and not being paid.
Does he have anything in writing? most companies have dates, 3 days, 7 days, and it should state with or without pay. If it does not state without pay, he should be getting paid.
I have been through this, and it sucks, I worked for a large medical group, and one day I came into work and they said that I would no longer be a supervisor, ( with that said I had never been written up or counsel and had just gotten a merit increase and a great yearly evaulation) that a nurse would be doing the supervising of my department ( an non nursing dept) but that I would be still continue to do the same work and all the same job functions, (I too held the license). and on top of it they moved me to a hourly job class, which was great for me as I worked aobut 50 hours a week, once they realized what kinda time it took to do my job, then they wanted me to stop working all overtime, I said okay no problem, but who is going to do all this work, and the Administrator said that the supervisor would, Okay by me!!! It wasn't a week and thing were not getting done, programs were not happening and then they wanted to change me back to salary , I said No, I am not the supervisor, I want to stay hourly, I was making the same money as when I was salary, so good for me, same money less hours.. No way.. I will stay hourly. The whole time all this was going on I was looking for a job. Once I found one and resigned, effective right then, Boy Oh Boy did that start a S@@T storm, I had people from the The main office's calling me, and HR directors. AS when I left I had called my licensing office and the state to tell them that I know longer worked there as I am required by law to do so. They offered me more money and said they would give me my title back and were then kissing my butt trying to get me to stay. Then when they found out that I a turn in my license change, this then casued another round of calls, in one of the call the HR manager told me that the only reason that they moved her is that they wanted someone else for her job, and thought that I would be okay with the change and for me to come on back to work, with a nice fat raise and more vacation andmore benfits. I laughed and said Thanks but NO Thanks...
I wish you and your family well, When God close one door he always opens a window. Sending Prayers and Pixie dust your way.
