Food delivery courier Joao Paulo Teixeira, 20, takes a mandatory selfie holding the bag of the food delivery app 99Food at the city center of Rio de Janeiro, Brazil, on April 17, 2026. Clad in Bermuda shorts and flip-flops, Joao Paulo Teixeira zips through the traffic on his electric scooter to deliver a meal in downtown Rio de Janeiro. The 20-year-old Brazilian belongs to a booming new professional class of delivery workers -- precarious by nature but increasingly organized in defense of their rights.
