In any case, Jennifer is correct in most cases. However, Florida Small Claims doesn't seem to restrict their cases solely to direct monetary issues as some other states do. (I might add that her response is still correct, since the original writer didn't provide a location for this claim... only that he/she lives in Florida. And even that doesn't show when posting a reply!!).
So, lets have a reality check to the original issues:
Q1) "Can a Supervior be Sued for Slander and giving False
statements?"
A1) "False statements", no. "Slander", possibly. But this is a very complicated (and difficult) case to PROVE that you have been slandered and even moreso, that you have been damaged by this 'defamation'.
Q2) "if so what Factors would have to take place?"
A2) As noted above, this type of case is VERY hard to bring and to win. It takes a LOT of legal expertise (read MONEY). As for asking "what factors", that is like asking "how much is too much?". No one can answer for you without a complete evaluation of the full circumstances and the claims being made.
Q3) "in order to take that person to Small Claims Court."
A3) Though not worded as a question, it follows a '?' making it a 'new' sentence, so here goes: As noted above, this type of case ('defamation') is VERY hard to prove and prosecute in a 'normal' court.... and even harder in a Small Claims environment where the defendant can simply say, "Your honor, I NEVER made the statements (or took the actions) that the plaintiff complains about". Without evidence, witnesses, pre-trial discovery, depositions, etc. you would have ZERO chance (in my opinion).
