If you want to quit the job and get unemployment benefits while you are looking for another job, you need to be able to answer the question, 'What did you attempt to do to solve the problem before you quit?" If the employer is totally unaware, you did not give them a chance to fix the situation, because you were all into how bad you'd been treated and yada yada, and you never told your HR, and they were never even aware that there was something going on or that you were having problems at work. In any type of sexual harassment legal action, or EEOC complaint, if you didn't tell your employer, you're really not going through the channels, and they have such an easy out. We didn't know there was a problem. Sorry. If she had told us, we'd have fixed it.
You will end up with no job, no unemployment insurance, no credibility, and those jerks who may have wished you ill will have won, thoroughly. And it will be very tricky to get another job, especially since you might tell the next place why you left this job. You must live in a verysmall place, if anyone in God's world is interested in some else's sexual behavior in high school twenty years later! That will mean that there are only a few places to work in your area. You have a decent job in a decent place, please don't quit and walk away without at least attempting to stand up for yourself and solve the problem. You can't take them to court and have your big day of justification if you never told them there was a problem.
