Food delivery courier Joao Paulo Teixeira, 20, checks the address of his next client on 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.
