I snarked on that, also, but to be fair, the expert is a doctor of psychology, and really is an expert on what kind of people go boom in the workplace. I think it's just poor writing, by the journotard.
Surprisingly enough, the workplace expert sees a chance of escalating behavior, from someone pooping in the hallways, today.
In my particular workplace, a notice was stuck in our bathroom wall over Christmas, to have a care, and not mess it up. I asked maintenance what the sign was about, and he said someone was throwing their poo all around, messing up everything. It was guessed that it was one of the temps that came on around Christmas, when our workplace become more...diverse, shall we say.
