My question involves labor and employment law for the state of: New York

Hi , I was fired today because of comments I made on my PRIVATE facebook page. I did not name the company in which I worked in nor do I have them listed as my employer. Someone at my job who I had as a friend on this social network went and told people what I said which was basically " I dont want to be at this place anymore , they do not pay me enough to work hard anyway. " this was told to the boss he didnt even see it. I thought to myself that isn't this freedom of speech and invasion of privacy ? I was not in any way slandering the company by name but just expressing my feelings on how crappy my job has become. The person who fired me said and I quote " I dont give a **** what you try to tell me , all I know is you were talking about this company " I continued to explain to him I am allowed to complain about anything I want and never named the company by name. He did not care. Now several hours later he had his underling call me to come back in tomorrow at noon. I am figuring that maybe he jumped the gun on getting rid of me and when he talked to company lawyers they may have told him it was not a smart move. I dont know what to do now..I definitely do NOT want to go back because of this. Is there any platform for a case ? Mind you I have been with this company over 13 years.
