my bosses are deciding whether or no i should be fired and are requiring a written statement from me between a conversation i had with another manager

The short answer is probably if you want to keep your job.  In Massachusetts, in the absence of an employment contract, you are an employee at will.  You may be let go at anytime without cause, as long as your termination it is not discriminatory in nature.   This sounds like there is an issue that management is trying to resolve.  If you fail to comply with their recommendations, they may fire you and you'll be without legal recourse. Good luck.
