My Husband Is A School Bus Driver In Alaska And His Company Made The Mistake Of Not Filing His Papers Federally Which Is Costing Him The Promotion They Just Trained Him For.

Sooooo my husband is a school bus driver and has been for the past 3+ years. I'm trying to see if anyone would be able to give me any insight on a very complex situation. He was just training the past month to become a BTW (a teacher who trains new drivers) well...... they sent him to the DMV to get his BTW license after he did all the work and finished his classes. This past Friday his company pulled him aside and told him that one of the employees messed up BIG TIME.... when he got his CDL from the DMV back 3+ years ago, one of the employees that no longer works there never sent in his papers federally. So he's not showing up anywhere in the federal system, and they said that means his license technically wasn't even "legal" the entire time. Now the company is rushing him through the loops to try and get a brand new license and sounds like they are trying to cover their tracks. My biggest issue is that #1 it will not show he has 3+ years of prior experience, and #2 they are now stating that he actually cannot become a BTW due to THEIR MISTAKE of the companies employee that failed to send in papers to the federal government. Is there anything my husband can do to get this fixed?! Can we legally sue the bus company he's working for?! And if so under what grounds? Would it be covered under the "equal opportunity employment act" I feel so bad because he loves his job, and was so excited for the promotion only to be told that now he can't actually be promoted now because to become a BTW is when the state part and federal part come together to give him the BTW license (That's how they found out to begin with that he's nowhere in the federal system). They said that when they found out the error that technically his license should have been suspended and now they're having him start from square one from getting a permit, a new license ect. But again his 3+ years of experience will not be valid. This is just so insane to me. I hope someone has an understanding as to how this works and if there's anything we could do to make this right. It's still all pretty confusing to me, if I'm being honest, because the DMV is also at fault for giving him the license without seeing the federal papers too it sounds like.
