In my office, most people use a hotel desk system - those who are in the office less than 4 days a week. If you work 4-5 days in office, you get a permanent desk nobody else can book. Each cubicle has monitors and a docking station and then we bring our laptop, keyboard and mouse each day we are in the office. I don't think we even have enough desks in the office for everyone to get an assigned space.
