Quite simply, desk booking is when you digitally reserve desks, areas and locations that are shared with others, like in shared offices or offices using hot desking where workers move around the office freely instead of having an assigned space. The idea is that instead of rushing to the hot desking office to grab a spot, you can book your desk in advance. Similarly to room booking, you can see which desks are available and can book it on the spot on the desk manager.
