Total lack of professionalism. For a journalist ("executive editor") such behavior is career-hurting. For someone in PR ("communications specialist") it is career-ending. I will come off sounding misogynistic here, but more times than not I have to put the blame at the foot of the woman. The guy comes after the woman for a date, it's her place to either say this will interfere with our business relationship or it's at least something we should reveal if it gets serious. If she's going after him, well, the one area women are employed more often than men is PR and people in those types of positions should know better.
I understand that all of this falls under the umbrella of larger issues, I'm just commenting on this particular incident. My father was a politician for many years and before that he worked as a PR liaison for many more. I have my own opinions about how f'd the system is in that regard but I also know the realities of how people behave. You simply can't be expecting others to take you seriously on the one hand while completing ignoring the duties that come with the position on the other.
