Thank you for your reply and sorry for the delay, seems like the posting notification is slow at the moment.
If the purpose is to sue, you would need to demonstrate "harm" to your person. I understand there are dirty looks from these ex-staff members, but that is not legally something monetarily you can recover for. If the statement disclosed had caused you to lose potential employment that you qualified for, then that would be harm to your reputation that could have been recovered.
If the goal is to clarify the issue with personnel, you can submit a report to be included in your personnel file. It should provide objections to the statements made and to set the record striaght on the termination of employment. Having this on record would help in case false information was being disclosed to prospective employers as those files could be subponed if you ever have to sue for an actual defamation cause of action resulting in harm to your reputation and ability to find employment.
I hope this makes sense.
