What is the difference between wrongful termination and being fired?

Wrongful termination by itself is not a legal claim. An employer is only breaking the law if they fire you for discriminatory or retaliatory reasons. New York is an at-will employment state that means an employer could fire you for no reason or any lawful reason and with no notice. If however, the employer fires you because you fall under a protected status or you complain to some type of unlawful conduct that is unlawful.
