OP here. I suppose I am really worried about No.1 Sprout who is a new PhD clawing her way up an academic ladder. Thanks for clarifying that for me. Of course, she could handle it, I think when I am in my non-mother mind, so I can also reasonably suppose these other women can, too.
I am invulnerable as I am not employed by Huge U. I could pull out his hair and scream to high heaven if I wanted to, or grab and twist somewhere lower (evil Lotus) but that would not be polite. I also have no authority whatsoever, for the same reason. What I have been saying sounds just about right, but I like the idea of looking at him like he rose from the swamp and adding, "So sad." Warms my heart just thinking about it.
The idea of getting Professor Plum, who is bullit proof, to get the Powers That Be to include more about sexual harassment, which runs both ways, under social guises in orientation materials and doing a push on those sections of the employee and student manuals sounds great. He can use Sprout # 1 as a backstory reason, if he likes, to bring this on. She is in neither of these fields and at Far Away U, so that is OK.
I would not advocate my personal tactics to others, of course, in reacting to unwanted grabbing. However, they have been successful enough to make the situation unlikely to recur <g>. Ok, I will put something into motion, keep my mouth shut as far as speaking directly to others are concerned, and practice my "you are an alien from a very strange planet" look. "So sad." Can't wait to use it.
