The only times I've ever had a drama free workplace was:
At the beginning of my career when I was an intern. They didn't care enough about me to include me in the gossip, and I was only going to be there for a few months anyway.
When my last job started letting us work from home, so I was no longer stuck at a desk in a high traffic area where multiple people would stop and chat. Headphones with a mic were a godsend, because when someone would start to approach, I'd just smile and point at the mic. Kept a lot of the gossipers at bay, though not all. WFH eliminated all that, I was so happy I could finally just focus on my work and not get caught up in situations that didn't even pertain to me.
