That is a terrible situation. Please go talk again to an employment lawyer. If you cannot do that, then go talk to the EEOC (Equal Employment Opportunity Commission). It appears to me that you have a classic "hostile work environment" sexual discrimination case brewing.
Good luck. Now please go get some legal help. Do it for your health and your loved ones.
I agree with the previous poster. You need to talk to an attorney. Keep looking until you find one who will take your case. You might also have a claim for unpaid overtime. In some situations, people on salary are entitled to overtime. That might be worth looking into.
Whatever you do, don't quit your job yet, even if you find another job. Get an attorney first to advise you on things to do before you quit that will help your lawsuit.
This is a terrible situation, and you really should not put up with it. Why on Earth are you resorting to looking for help on the internet, instead of calling a lawyer? Get to work on a few different tracks. First, start looking for a different job. You are never going to feel good about working at that place, and you should put your mental and emotional health first. There is no shame in walking away form an abusive situation and finding a better situation for your health. Second, what kind of "waiver" did you sign? Are you really just saying that you signed an agreement to keep your complaint confidential? Make a written request for a copy of your personnel record file, submit the letter to Human Resources (make a copy for your files), and don't take no for an answer. You need that file to show your employment lawyer. Also, make a copy of whatever sexual harassment file is on the intranet, if you can. Show that to your lawyer. Third, pull out your employee handbook, find the sexual harassment policy, complaint procedure, and anti retaliation policy, and go to the Human Resources Vice President or Manager and make your complaint. The the whole story, have specific details memorized, dates and times, specific things that were said, and have your witnesses lined up ready to talk when HR does their investigation. Fourth, there are several good plaintiff's employment lawyers in Philly. Try the National Employment Lawyers Association website (www.nela.org) if you can't find a lawyer that specializes in employment rights.
