When there was a long period of 100% remote during Covid, there were some issues:
- Spontaneous interactions: Someone complaining over the lunch about issues with some library, just as a small talk. Someone else says, "hey, have you tried X instead?". Someone joking about product feature that actually ends up being a good idea. Ask for some feedback on what you're working. Discuss some issues over the lunch. In remote-only setting, everything requires setting up a meeting. That often formalizes everything, and less things end up being discussed.
- Morale : Working with everyone in the office is somehow good for team building. Maybe Morale was lower just because Covid was bad for everyone, but most people would admit they experienced it.
- Developing team connections: If you know someone in person, it feels easier to ask them for help, etc. Some ideas posted online, like shared board game via zoom is really far away from in-person interactions.
- Some people are quite good at focusing at home. It varies person by person. We have some people, who are great at fully remote work. In my case, when I am at work, I am working. When I am at home, I much often end up doing stuff like reading HN.
I am not saying it's not possible to work around those somehow. We tried several ideas posted online, in some books like REMOTE: Office Not Required, but it didn't work for us.
