It’s the nature of people, but I think you’re going to find it in some jobs/industries more than others. I work for an aerospace company, and they regular tell people they shouldn’t be discussing things like politics and religion at work. We’re not allowed to wear shirts or put up things that are political or divisive. Stuff like that doesn’t eliminate the drama, but it helps. Also, engineers don’t tend to be overly dramatic types.
When I was young I roadied for a friend’s band, and so was hanging around a lot of musicians and artists, and the amount of drama was kind of insane.
