Food delivery: very low-paid, zero job security, and, if you do it on a bike, brutal on your body. There’s a reason why most “riders,” as they are called, count their time in the food-delivery sector in months, not years. The industry chews up and spits out workers at a rapid rate, knowing that many of those who stay don’t intend to stay long: riding is a stopgap, a means to sustain themselves while they look for something better, and the working conditions are bad.

Food-delivery bike riders in London, Berlin, and Copenhagen are pushing back against their algorithmic bosses.
