Uber drivers are commonly referred to as workers in the “on-demand” economy.

But on Monday, weeks after Uber announced that it was slashing prices for rides in cities across the country, hundreds of drivers gathered at the New York City headquarters of the ride-hailing service with a demand of their own: restore prices or face a backlash.

Tsering Sherpa, a Queens resident who said he drove for Uber six days a week, eight hours a day, predicted the fare cuts would force him to work 10 to 14 hours a day to make his rent and car payments.

“New York City just keeps getting more and more expensive,” Mr. Sherpa said at the rally. “How are we supposed to survive with less money?”

“They call us partners,” he added. “But they’re treating us like slaves.”

It was a sentiment shared by others in the crowd but one that Uber officials called unfair on Monday.
