A company the USA is paying its employees to sleep more. Staff the insurance company Aetna will get $300 a year added their salary if they get least seven hours sleep a night. That works out to just over an extra dollar each night the employee sleeps seven hours. The idea behind this scheme is employee performance. Human resources officials say employees will work better if they have slept well. They add that a workforce that is more awake and alert will mean the company will perform better. Staff can either record their sleep automatically using a wrist monitor that connects Aetna's computers, or manually record how long they have slept every night.

There are a number studies that warn that not sleeping enough can affect our ability to do our job. The American Academy Sleep Medicine said that the average worker the USA loses 11.3 working days productivity a year because not getting enough sleep. This costs companies about $2,280 for one worker. It estimates that the US economy loses $63.2 billion a year because workers do not sleep more than seven hours a night. A 2015 study Europe the Rand Corporation found that staff who slept less than seven hours night were far less productive than workers who had eight or more hours sleep. The staff Aetna also receive extra cash if they do exercise.
