If you are an at will employee, your employer can change the terms and conditions of your employment at any time for any reason, or for no reason, upon notice to the employee. Your choice is to quit, or to continue to work under the new terms.
If you are not an at will employee, it is altogether different. For instance, if your written employment agreement guarantees you employment for a period of time, or says you can be terminated only for good cause, then you are not an at will employee. If that is the case, and if you are let go, you should locate and consult with an employment law attorney to determine your options.
Good luck to you.

I agree with Attorney Pedersen:
You and your colleagues should ask a knowledgeable lawyer to analyze the employment agreements and explain your rights under those agreements.
