To be honest. If I was actually standing there and observed her posing for this shot...while I would roll my eyes at yet another "douchebag" in the world...I doubt I would have bothered thinking much more about it.
Again. Is this really "new" human behavior or is it simply "tar and feathering" in the digital age?
Exactly. I'm certainly not joining the bandwagon to crucify the woman. Should her company discipline her for screwing around when she was on the clock, in a manner that has come back to reflect poorly on them? Yep, if they want. Should that discipline include termination? Probably not, unless there are other problems. And if they choose not to do so, to essentially say that "yes, it was company travel, and a company activity, but it was done on what amounts to break time", well, that's there business, as well. Might be some unofficial sanctions, like not getting to be included on the next trip or squashed promotional options, until her judgement improves.
I'm rather more concerned with the general atmosphere that says a 30 year old woman should pull high school stunts, though. That's more of a problem to me.
This seems to be the kind of thing that a person with some maturity might have thought of -- and then went "nah, too juvenile."
