US restaurants are on track to take a $50 billion hit in April, with losses mounting to an estimated $240 billion by the end of 2020, as the coronvirus crisis ravages the industry, according to a National Restaurant Association survey released on Monday.

Two thirds of U.S. restaurant workers — or 8 million people — have been laid off or furloughed, according to the study.

Approximately four in 10 restaurants are closed, it says.

Unfortunately, at least 60 percent of operators say existing federal relief programs will not help them prevent more layoffs, the survey found.
