Their three-hour lunch breaks have long been the envy of workers in neighbouring countries, their business meetings often start late and millions of them rarely get to bed till well after midnight.
But now Spaniards face growing pressure to give up their siestas, bring their working day into line with the rest of western Europe - and switch their clocks to the same time zone as Britain.
A parliamentary commission has called for fundamental reform to traditional working hours and practices as part of Spain's effort to break out of recession and reduce the chronic unemployment that has dogged its economy for the best part of a decade.
The review, by the National Commission for the Rationalisation of Working Hours, is expected to win the backing of a panel of MPs on Thursday.
"We need more flexible working hours, to cut our lunch breaks, to streamline business meetings by setting time limits for them, and to practise and demand punctuality," says the report. » | Martin Roberts in Madrid | Monday, September 23, 2013
