Once you sign they don't have to pay you! They may decide to make you go to North Carolina, their home court, where their lawyers are familiar with the judges. They could also make up anything they want in their electronic record about you; thereby, making your hard evidence worthless. They could even invent criminal charges against you.
I would suggest filing a class action lawsuit across the country as everyone was fired shortly before the annual bonus. I am currently working on charges of Retaliation before the act that may set a president.
Please bear with me as I'm trying to find a suitable attorney who will take this all the way to court.
