"Don't look?" Exaggeration, Ms. Dotterrer (or is it Mrs. or Miss, please)? This isn't about looking. 
Any woman that wears a  regular blouse or modest dress can, in certain stooping activities, expose parts of herself she'd blush to have frozen-in-time by a photograph (this also goes for sitting down in a dress or skirt). For a supervisor even to think of doing so to a subordinate is not only introducing lewd behavior to the workplace, it is demeaning his employee and subjecting her to ridicule and future abuse--"Hey, the boss does it!"
I suppose, with the fellow in the White House who boasts of groping women, some folks have found they have to defend similar behaviors or be thought hypocrites. I wonder, truly, how much Dotterrer would like to have had a compromising picture of herself shared among her fellow workers. Or, how about one of her daughter?
The shocking thing about this story is how long it took for this creep to get disciplined. Kern should be nervous about a lawsuit...
