I'm not sure if you saw my questions. I asked because they are legally significant.
In employment law, you can legally be terminated at any time, with or without cause, unless you have an contract stating that you cannot. This is called "at will" employment and it is the default employment status for all states in the U.S.
So legally, you could be terminated for job abandonment, at least for the employer's purpose, making the termination legal. Unless you can allege discrimination based on one of the factors I mentioned before, the termination would be legal in the absence of a contract of employment that very explicitly states you can only be terminated for cause.
So your fight here is only for unemployment. You can file for unemployment, argue that you were released so this was not job abandonment, and the employer can't claim job abandonment successfully. All that would entitle you to though is unemployment. The termination itself would remain legal and it doesn't create any sort of Department of Labor complaint, at least based on the facts in your initial post.
This is why I asked the questions...to see if I was missing anything.
