Drinkaware said its research indicates 520,000 British workers arrive for work each morning while feeling the effects of the previous night's drinking, and one in five admitted hangovers get in the way of their productivity, Sky News reported Wednesday.

Chris Sorek, chief executive of Drinkaware, said hung-over workers can be a serious drain on a company's productivity. "With hundreds of thousands of people going to work every day after a heavy night, it impacts work productivity and even results in employees going home sick," he said. He said alcohol consumption is expected to increase during the upcoming World Cup soccer tournament, leading to further issues. Sorek said Drinkaware is working to educate British employers on methods of dealing with problem drinking among staff members.
