Some might consider domestic employees the original gig workers. There are a lot of similarities, like intermittent income and no real safety net. It's a problem that affects millions of workers like nannies, caregivers and house cleaners, and the National Domestic Workers Alliance is working on solutions. The group's innovation arm, NDWA Labs, is bringing financial tech to domestic workers. Its new platform, called Alia, directs digital payments toward benefits for house cleaners. Marketplace's Leila Goldstein talked with one cleaner who uses it. Today's show is sponsored by the University of Florida Warrington College of Business and Brother Printers.
