Shares of Uber Technologies Inc., Lyft Inc. and other “gig-work” companies dropped sharply Thursday after U.S. Labor Secretary Marty Walsh said most gig workers should be classified as employees.

“We are looking at it but in a lot of cases gig workers should be classified as employees,” Walsh told Reuters in an interview. “These companies are making profits and revenue and I’m not (going to) begrudge anyone for that because that’s what we are about in America… but we also want to make sure that success trickles down to the worker.”

Those appear to be the first public comments by Walsh on gig-worker classification — an increasingly important issue that has broad implications for the future of work and what have become some of the nation’s most well-known companies.

In California, gig companies banded together and spent more than $200 million to fight a law that would have required them to classify those workers as employees, putting an initiative on the November ballot that was passed by 58% of the state’s voters.

Walsh, a former union leader, is expected to bring more teeth to U.S. labor laws under President Joe Biden’s administration. Biden himself said during his presidential campaign that he would “put a stop to employers intentionally misclassifying their employees as independent contractors.”

Gig workers’ classification became even more of a flashpoint in the past year, as the coronavirus pandemic wiped out demand for ride-hailing for months. Gig companies do not pay into states’ unemployment-insurance systems, and drivers were able to collect unemployment benefits only under the federal pandemic unemployment assistance program.

Walsh told Reuters: “If the federal government didn’t cover the gig economy workers, those workers would not only have lost their job, but they wouldn’t have had any unemployment benefits to keep their family moving forward… we’d have a lot more difficult situation all across the country.”
