 From NPR News, I'm Ari Shapiro. And I'm Elsa Chang. A nationwide ban on non-competes is set to take effect September 4th. Those are agreements that prevent employees from going to work for a competing company or launching one of their own. But legal challenges to the nationwide ban are making their way through the courts. And this week, a ruling from a federal judge in Texas could put the ban on hold. NPR's Andrea Hsu talked to two people with differing hopes about how this legal fight will end.
