Civilian job fired me

Hi all, I’m currently on ADOS orders and have been on orders since June 2023. I gave my civilian employer a 2 weeks notice before I started my orders and they let me go on a leave of absence until my orders were up. I provided them my orders, the USERRA Employer information, and a point of contact in case they needed to reach out about anything.

Well, I woke up this morning receiving an exit survey email from my civilian job. I checked my company account online to see if i could log into it and they’ve locked me out. I’ve reached out to one of the managers there that i’m close with to see if i got fired or get any information but no response. I’m so confused because no one has reached out to me to tell me i’ve been terminated. I reached out to the Department of Labor and they said I can go three different routes: -contact my employer and figure out what happened and how this violates USERRA
-contact the ESGR - or file a claim with DOL-VETS

I’m not really sure what to do here but I would prefer not to contact my business manager as she is kind of aggressive. I’m kind of thinking of filing a claim but i’m not sure what happens after that. I certainly do not want to go back to that job if this is how i’m going to be treated. What do you guys think?
