Sexual harassment

My wife was recently 'forced' to leave her job due to repeated sexual advances and lude behavior by her boss. He would repeatedly corner her, rub up against her, look down her shirt or rub her leg while they were attending to a patient in the dental chair. They worked 4 days per week and on their off days he would call the house and make sexual advances to her over the phone. He would also give her gifts that the other emplyees did not receive. When she did let him know repeatedly that his actions were inappropriate and unwanted, he would ask her, 'where else are you going to get a $17.00/hr job and have time off to be with your terminally ill father?' These actions by him went on the whole time she was employed by him, 5 mos. Apparently there are others in the workplace that have experienced these same actions. On the day she left, he offered her $10,000 after she threatened to file a lawsuit.It is a single Dentist office where he is the boss, employer, etc. She has had trouble sleeping, eating and has been very irritable.

Does she have a case?
