I am a CFO/Tax Collector of a NJ town facing a hostile work environment, and may need legal counsel

For over three years my department(s) have been enduring a hostile work environment, and came the moment in which I realized that I should've probably done something about it long ago. The sort of hesitation has been my doubts about how productive potential legal action could be in a situation that might also involve whistle blowing. Essentially I report to an egotistical micro manager, who has been running the affairs of the town as a mom and pop shop for over a decade with the strong support of the most senior member of the governing body, a crooked but personable and affable politician; obviously both of them indulge in certain benefits as a result. There is a well-orchestrated pattern of actions leading to not only debilitating the statutory functions of the CFO, but to take them over hostilely and basically downgrade my core duties to a simple Accounting Clerk, in order to obtain large pecuniary benefits in the process; it is an elaborate scheme with even racial connotations.
