During the early 1980s, when I was working full-time in Corporate America there were all sorts of career articles on how to deal with The Office Pest. Usually departments had at least one or several of different kinds. Those included Complainers, Compulsive Talkers, The Boaster about professional accomplishments, and Borrowers of everything ranging from money from co-workers to office supplies.
That was then. Not since the onset of the downturn have I heard any of my acquaintances mention any Office Pests. Survival instincts seem to have sprouted up. Those who would have normally been the Office Pests have kept those offensive behaviors under wraps. They're not going to take any risks with having a real job.
