I'm currently in a team that works pretty much 0800-1600, people mostly start logging off 15 minutes before four and after four everyone is either at home or packing their stuff. (Or playing a game if they're WFH :D )

There's zero pressure to work overtime and leaving on time is encouraged. If people work late, we encourage them to leave earlier and relax. Not all tasks can be solved with brute force head smashing.
