I would go back to office if my commute was like 20 minutes by bike and I would share a small office with one to three other people on my team.
But my commute is 1 hour one way, some people don’t get seats on the train, U-Bahn in Berlin is like a can of sardines during rush hour and the bigger part of my team is in another country and the customer is at the other side of Germany. And the office is one big open office with ~40 people working. You need noise canceling headphones to keep your sanity. I couldn’t focus without them.
I‘m glad they don’t want to force us to come back.
