Who is working on that project? Who has a closer parking space? Who is going to training?
These are the topics some of my coworkers can discuss for years. Every time I hear about these rampant discussions I am always surprised. The words "adult" and "professional" don't go hand in hand with petty, passive-aggressive discussions.
Inevitably, people pick a side and run with it. Of course on the few occasions they are called on their pettiness, they act sincere and innocent. They always get away with it which is why this behavior continues.
I thought high school ended at graduation.
