Are there other people around, when she corners you like this?! Where does she ever find the time, to do this?!

Who's working around there, if all she is doing this to you?! She reports to your Brother in-law, and have you told him, yet?

I agree with the above poster, be very direct and clear, "Listen, keep your hands off me, or I will report you to the Board of Labor!!" (and while I am at it, why not the other employees, your husband and whoever else. While I'm at it too, here, let me video record this on my cell phone, while I say No!!)
