What are my rights attorneys preferred?

Ok here it is I have been working for a state run hospital for 4 months and there are 3 guys there that do whatever they want with our boss never doing anything to them however when they started saying things to me and about me I stood up for myself and said something to the management a few days went by and they walked in cornered me and aulted me I then turned them in again going to even a higher management and a few days after that found out the only thing got done was management had told other people that had nothing to do with our area like it was funny or something. I requested a few meetings to resolve the issue however it does not seem to phase them I have doented all the actions those persons have done to me which includes time date who witness it and what accrued what should i do and what more should i doent i also recorded the meetings which i believe i can not use which shows the people admitting to the acts and management still don't do anything about it what are my Legal rights here
