Do you plan on having Friday being a day to wrap up the current week or set up the next week?
Do you just go with the flow and have little to no structure?
Personally, I work quite late on Thursdays and use Friday to kickstart the next week so I can dive in Monday morning. Make sure all my ducks are in a row before the weekend. I also have coworkers who barrel through Friday and use Monday as just a stop-and-gather sort of day.
Curious how others have their weeks set up.
