I work in an office that has few to no spare desks at the best of times. It is crammedrammed!
However, there tend to be desks within the office that are free (due to holiday, business travel, working from home) but people are reluctant to sit at them as they do not know that they are free.
We have tried making colleagues aware that they should take a 'hot-desk' laminate from reception when vacant and put it on their desk. This didn't work as expected as people either didn't comply, or the signage wasn't obvious enough among the sea of desks.
I was wondering if you have encountered ways/ can think of ways that people can let others know that their desk will be vacant - whether the following day or part of the day - to help keep usage of office space as efficient as possible.
