Employees at Goopal Group take a nap in their seats after lunch, in Beijing, China, April 21, 2016. Office workers sleeping on the job is a common sight in China, where a surplus of cheap labour can lead to downtime at work.

Some companies provide sleeping areas and beds for workers to rest during late nights. REUTERS/Jason Lee SEARCH "JASON SLEEP" FOR THIS STORY. SEARCH "THE WIDER IMAGE" FOR ALL STORIES
