Hot desk etiquette is the set of ground rules that keeps shared desks pleasant: leave the desk clean, do not camp on the same spot daily, take calls in booths, respect bookings and check in so unused desks release for others.
Etiquette works best when the system enforces the boring parts. Auto-release handles squatting on bookings, sanitisation can follow check-out data, and neighbourhood rules encode where teams sit, leaving humans only the genuinely social rules.
