Lawyer to Litigate Against City

I was hoping to inquire the Edhat community about finding a good lawyer. My particular situation would involve litigation against the city, specifically in regards to an unethical workplace where emotional distress occurs and illegal activity happens. As is obvious, I’m not certain which type of litigator can take on my case, which does concern itself with discrimination, nepotism, drug use by fellow employees, amongst other complaints and concerns. Just FYI, I am not the only person (as in, city employee) willing to sue.
