I hope this message finds you well, present circumstances excluded. I am a licensed attorney with over a decade of legal experience handling matters such as this one in the employment sector. It is a pleasure to assist you today, though I wish the circumstances were different.
In short, there are not many legal rights here for you. I assume based on your description that you are an at will employee. This means that the employer can terminate you or eliminate your position for any reason or no reason at all.
There are, however, a few exceptions to this doctrine. A company cannot adversely affect your employment based on discrimination or based on things that would violate public policy (termination because you refuse to engage in illegal activity).
If you feel as though you have been negatively affected because of your race, gender, age or because of a disability, then you may have a cause of action. If that is the case, then you can file a claim with the EEOC against the company in the US. They will investigate and if they find merit, will allow you to sue in federal court for damages and attorney fees.
Otherwise, based on what you have shared with me, there are not many, if any, avenues of recourse for you unfortunately.
Let me know if you have any other questions or comments. Please rate my answer positively (three or more stars) as well so I can receive credit for my work.
Best wishes going forward!
