Once lawyer has extracted what s/he can from the company and settlement doesn't prevent you from further pursuing, send complaints to department of labor and state attorney general. While DOL and AG office most probably will not do anything, The complaints will go on file at both offices. If the company is pulling similar stunts with other employees and DOL/AG office sees series of similar complaints, they may go after the company.
Privately bad-mouth the company to your network (not intentionally), word gets around and will warn others. Make sure you never work for another company connected to founders and senior executives of this company. Unethical management and investors at the top attract unethical people and breed unethical culture, they will never change their behavior.
