It depends if the statements are untrue. A person is defamed when one person communicates a lie or makes a false accusation about another person, either orally or in writing, to a third person, which cause damages to the person's reputation. A company - in order to carry on its business efficiently - is entitled to what is known as a "qualified privilege" to make statements about its employees regarding discipline, termination, and references. It is not enough that your employer made a false statement about you. The person making the statements must have acted maliciously or known the statement was false or was reckless in determine whether the statement was true or not. If your employer gives an unfavorable opinion about your work to another person, you do not have a claim for defamation unless your employer states that the unfavorable opinion was based on a fact which is not true and which damages your reputation. Opinions generally cannot be the basis for a claim of defamation If you suspect that your former employer is giving out a bad reference, have a friend call and ask for information about you. Your friend may be able to confirm your suspicions.
