Everyone can get a little emotional at times. Be it from a bad day or from a disparaging remark from a co-worker or boss. No matter the reason, it is always better to walk away from your cubicle, away from the stares of co-workers to have a moment, shed some tears and recollect yourself.
Crying or being overly emotional can be seen as a sign of weakness as an inability to handle the stress of the position. Not the message you want your boss to get, particularly before a review or during your next salary discussion.
This 2005 article from the New York Times, discusses crying at work bluntly. Unable to find an article referencing the rampant crying of the secretarial staff in the bathroom of Sterling Cooper, this commentary on AMC blogs will have to suffice.
