Uber is feeling the heat from angry drivers.

In a conference call with reporters on Tuesday that focused mostly on the company's diversity efforts and its search for a chief operating officer, Rachel Holt, a regional general manager, said the company is addressing a rising level of discontent among drivers.

Declining fares that benefit riders have long made it difficult for drivers to make money. Holt said that Uber is fixing a bug that reduces pay to drivers when a passenger cancels a ride mid-route and is tweaking its rating system so that drivers aren't unfairly suspended.

"We need to give drivers a say in fare adjustments," Holt said. They should be "fully compensated for their time."

Uber, the $68 billion ride-hailing service, has been a house of controversy this year, beset my sexual harassment claims, rapid turnover among executives and CEO Travis Kalanick's previous ties to President Donald Trump's . Last month, Bloomberg published a video of Kalanick arguing with a driver, who was complaining that the precipitous drop in fares was causing him to lose money.
