Lots of gig workers earn tips. So, when InstaCart started paying its full-service shoppers and deliverers on a sliding scale based on how many tips they got, the workers were pissed off. They took to Reddit and Facebook to complain and gained the national media's attention. This month, InstaCart changed how it pays its app workers. It's seen as a victory for gig workers that have been trying to get tech companies to be transparent about how they pay so-called contract workers.
