Two hours of peak, and a rota built around them rather than around the day
A courier firm with three zones, forty drivers on the books and a dispatch desk runs two rushes a day: lunch from half past eleven to two and the evening from five to ten, with a late run until midnight on Friday and Saturday. Most drivers are part-time and work three or four short shifts a week; a core of full-timers takes both peaks in one day with the quiet afternoon between them; two dispatchers cover the desk from eleven to midnight in overlapping halves. Each zone has its own pick-up point, its own restaurants and its own regulars.
Without a rota built around the peaks, the zones drift. The north has nine drivers on a wet Tuesday lunch and the south has three; a driver who agreed to the Friday late run by voice message does not turn up; the dispatcher who was meant to open the desk at eleven is also down for a round in the east; and the hours of forty part-timers are added up from a chat history on the last day of the month.
Below is how a three-zone firm looks in InShift: every zone as a location on one screen, a Friday of peaks as a table, four more drivers found for a wet evening in one move, the peak paid as a shift with its own price, and the dispatcher’s day by zone on the phone.
