You need to hire a lawyer familiar with ERISA claims. (ERISA is the federal law that governs employee benefits.) Often that will be an employment lawyer but not all employment lawyers understand or practice ERISA claims.
If you call any of the Rutgers clinics and explain the situation they will put you in contact with the appropriate clinic, if there is one that handles those types of claims. The law school clinics are often needs-based so they will only assist you if you are below their income limits. If they cannot assist you then you will need to hire a local employment lawyer to assist you.
