I forgot MA was an at-will state. You pointed it out and I looked it up to check. I was agreeing with you. My second sentence was saying, if they fire you for no reason then they shouldn’t have anything on record to say about you that is bad.

They can fire you for no reason that is true. But they shouldn’t have anything bad to say about you then should though.

Yes but you can’t fire someone without cause so most employers keep records of complaints and violations. So as long as they only say why you were fired there is no room to argue

Yes but not if the remarks are true. They can say “oh we fired them for this” granted most places won’t unless you were really just a scum bag. All that being said putting a former employer down as employment history and as a reference are two different thing. You shouldn’t be putting someone down as a reference if you got fired

The reference can say whatever they want to
