Marriott International Inc plans to lay off 17 per cent of its corporate workforce next month as the coronavirus continues to take a heavy toll on the hotel industry.

The US-based company confirmed on Wednesday that it will lay off 673 workers late next month.

Marriott has about 4000 employees at its corporate headquarters.

Marriott furloughed two-thirds of its corporate staff in March as hotel demand plummeted.

Some of those workers are coming back to work later this month, the company said.

Marriott’s revenue plunged 72 per cent to $US1.5 billion ($A2.1 billion) in the April-June period as global hotel occupancy sank.

Marriott says some business travel has resumed in China and leisure travel has gained strength in the US but it doesn’t know when demand will return to 2019 levels.
