The Equality Commission's nonbinding recommendation, which urged commissioning a study of the economic consequences of a time change, will be considered by the full parliament.
The commission's president, Carmen Quintanilla, said the time change was "a foundation stone" of a series of recommendations aimed at making work and school hours more flexible and work and family life more compatible.
"We drag out the morning and extend our lunchtime. We lose time and have to work more hours in the afternoon. Eating later, we have to start work later, which means we get off work later," she said.
Although working hours in Spain vary greatly, the typical working day is divided in two, with lunches sometimes lasting up to two hours. Many workers take this opportunity to dine at home something health experts believe is beneficial and this in turn allows them to enjoy the famous Spanish tradition of the siesta.
But as a result, many workers do not get off until after 7 p.m. and shops stay open up to 10 p.m., when bars begin to fill for what are often lengthy nights of socializing.
"Our time schedules have serious effects on the daily life of Spaniards," said Nuria Chinchilla, a business school executive who helped write the study, adding: "We live in permanent jet lag."
