A quarter of Britain’s bosses are likely to be in a bad mood at work because of too little sleep, research released on Monday showed.

The study, titled “Dream On: Sleep in the 24/7 Society,” found half of sleep-deprived managers admitted to shouting at colleagues because of tiredness. Nineteen percent said they were likely to make mistakes.

“These sleep-deprived and shouty managers with a tendency to make mistakes are responsible for millions of British workers. It’s hardly a recipe for good management,” said Charles Leadbeater, author of the report for independent think-tank Demos and retailer IKEA.

Among the general population, 39 percent said they needed more sleep. Children were a main reason behind sleepless nights, while worries about work pressures and snoring partners were also mentioned as causes.

To solve the problem, the report suggested filling city centers with “shut-eye pods,” which would operate on the same principle as coin-operated toilets, allowing people to take a quick nap.

It also encourages people to nap at work and recommends awarding “catch-up days,” particularly to those with young children.
