What type of lawyer should i seek in a case regarding medical residency retaliatory harassment that resulted in my suspension from the program?

I have had no prior behavioral or disciplinary actions ever throughout my medical career, then in less than a week after i voiced some complaints against an attending (supervisor) I was suspended immediately for behaviors they said made me unsafe to work with patients and required I see a psychiatrist of their choice for a "fit for duty" exam with full report provided to them. Is this a violation of my civil or employment rights? no prior warnings or letters of my behavior were ever documented and the behaviors they stated included "smiling and laughing inappropriately". Since their action occurred 4 days after my complaints and as I have no previous behavioral issues, I think this action was a form of Retaliatory harassment at the level of the department chair. What types of lawyers should I start searching for to at least help me in the internal process the program is forcing me to go through?
