As an employer, if I had ten employees who all thought FHRITP was funny, and one of them got drunk enough to pull this stunt on television, I would consider that one out of ten had a serious judgement problem and nine had some semblance of socially reasonable judgement to not do such a thing.
I don't need my employees to think like me, act like me, or or like any particular brand of "acceptable" as defined by me or the company. I do not need to know nor care if any of my employees thinks FHRITP is funny.
I absolutely _do_ expect all of them to not go on television and demonstrate this level of bad judgement. By extension, I would now have two issues: first of all I'd question what other bad judgement comes into play in that employee's work product, secondly I'd be aware that _my_ judgement now comes into play as the responsible hiring manager.
I'm extremely sensitive to separation of work and family life. I demand the same from my employer. But I am wise enough to know that no matter what I do in the privacy of my own home, once I take that on a television news broadcast, I am in effect representing anything and everything the viewing public can now associate me with, whether it be my cycling club, my church, my darts team, my family, or my employer. (I only have the last two of those five, I'm straining for examples as I don't go out much...)
In short, where the conversation seems to be "OMG corporate thought police" it is in fact "seriously, keep that to yourself".
noun: judgement - the ability to make considered decisions or come to sensible conclusions.
