"Employees Who Enjoy a Drink Are More Productive"

From yesterday's Evening Standard:
Employees who are consume above-average amounts of alcohol are capable of working an extra ten hours per week, according to a study.
Women who knock back at least two glasses of wine in the economy clocked in nine-and-a-half hour plus days during the working week. Men who regularly drink three pints an evening were capable  of the same long hours.
Researchers studied 333,693 people from 14 countries and concluded that an 11 per cent increase in alcohol use enabled people to endure much longer working hours.
