A manager of a distribution center in Avellaneda put the problem to me bluntly: "I have 18 drivers who start at different points; some pass by the warehouse and others go straight to the first client. How do I know what time they actually started?". That question summarizes the sector's mess: the paper sheet stuck on the warehouse wall is useless when half the team never sets foot in the warehouse. Here I tell you how to record the workday for personnel on the road, what Argentine regulations ask for, and where the line is between clocking in and tracking.
