In CA at least all employment contracts are at will unless stated otherwise. It sounds like you might have an argument based on the above that your employment was not "at will". You should try to find out if someone else was hired to replace the senior citizens that were fired. That might provide you with enough to find a lawyer to take your case.

In Connecticut and New York, most employment is considered to be at the discretion of the Employer unless there is a written contract stating otherwise. There are also a number of exceptions to the at will doctrine in most states. If a persons civil rights are being violated [i.e. title IIV where someone might be discriminated on the basis of race, age, sex, religion, etc.,.] in the context of employment, then there may be certain remedies he/she may have. It is in your best interest to seek the advice of a local labor/employment attorney, based on what you have stated. I recommend that you consider www.nela.org to find such an attorney. Good Luck!
