A staffing manager walks into a café in downtown San Francisco and hands out small packages. Inside each one is an elastic headband with a phone mount. The instructions are simple: strap it to your forehead, go home, and film yourself doing the dishes. Roughly two hours of usable footage pays about $80. One longtime gig worker, who has delivered food and hung Christmas lights for a living, summed up the appeal without much ceremony — he has to do the chores anyway, so he may as well be paid for them.
