Severance For Other Employees But Not Me

I work for an LLC in Georgia. Our corporate office is in Virginia. A few weeks ago, corporate notified us that they were closing our office in Lawrenceville (metro-Atlanta). They indicated we would get severance. There are 5 full-time and one part-time employees.

My boss, who sold his company to the company we work for now in 1998, has decided to open his company again. He has offered me a full-time position. However, corporate has indicated that I cannot get severance since I will have a full-time job the day after I am laid off.

The other full-time employees are getting severance. They do not have jobs yet.

I have worked here three years longer than an employee who will get severance.

I guess there is no right to severance, but is is FAIR to pick who gets severance and who doesn't? Wouldn't this be covered under the Fair Labor Standards Act or some discrimination law? Thanks.
