Tech workers fall asleep on the job

Dai Xiang has slept his way to the top.

The 40-year-old Beijinger got his start as an engineer, pulling 72-hour shifts at a machinery company while catching naps on the floor.

After a switch to the tech industry and around 15 years of catching naps on desks and other flat surfaces, Dai co-founded his own cloud computing firm, BaishanCloud, last year.
