Truth is a defense to any claim of slander or defamation. I do not see a viable claim related to their actions assuming that no written or even quasi agreement existed between you and the employer.

I agree with Mr. Tan. Unless you had a specific agreement with your employer (preferably in writing) that the employer agreed to keep all such information you disclose confidential, you likely do not have a case against your employer. As Mr. Tan said, truth is an absolute defense to libel/slander, so unless your employer disclosed FALSE information, you would probably not have a remedy.

Yes, if there was a breach of employment contract regarding confidentiality or complaints. However, if you still have that job and want to keep it, let the matter go and don't respond- other than in as few words as possible such as: "It bothers me to even have to consider protecting my reputation and name, but X is blaming the wrongfully blaming me for this."
Next time something like this happens, Deny, Deny, Deny and then if you have to, blame it on the accuser. An example is:
I did not.
Whoever told you is wrong.
I would never do such a thing.
This is your problem, which you caused yourself- I actually did you a favor...
