I'll try to explain why each of the questions was important.
First, without an employment contract, your employment is "at will
." That means that the employer can legally terminate your employment with or without cause, at any time. This is true in your state and every other U.S. state except for one. So, typically, the termination would be legal unless there is an illegal motivation to behind the termination.
This is why I asked about discrimination
or whether or not you were a whistle blower. I asked about the FTC issue, because you mentioned they were under investigation. I asked about discrimination, because often people don't consider this as an issue until I raise it. They think that the termination, as unfair as it seems, should be justification enough for a claim and never look deeper. Well, in an "at will" employment situation, you have to look deeper, because even an unfair termination is completely legal without some underlying illegal motivation.
Finally, on the issue of these promised AMG services, that does not create a binding contract because you did not sign any document or give up any rights in order to obtain it. Instead, it was something being offered by the employer that they could legally retract any time. So, there is no way to claim that the employer was illegally trying to avoid giving you the AMG services when they actually had no obligation to do so even if they kept you on. Such a promise is called an illusory promise in the contracts and employment law
world, because there is no way to make it binding.
Regrettably, on the facts that you've given here, your only real recourse is to file for unemployment
and, if they attempt to block that, fight the issue before the unemployment court.
I do wish that I could tell you differently here, but in an "at will" employment situation the employer has great discretion in when and how they terminate people.
