The proposals were brought forward by the leftwing party Más País. The trial will see interested Spanish companies test reduced hours for workers. Iñigo Errejón of Más País announced on Twitter: “It’s an idea whose time has come.
“With the four-day work week, 32 hours, we’re launching into the real debate of our times.”
Mr Errejón added: “Spain is one of the countries where workers put in more hours than the European average.
“But we’re not among the most productive countries.
“I maintain that working more hours does not mean working better.”
Across the world, from New Zealand to Germany, the idea has been steadily gaining popularity.
Proponents of the idea said it would increase productivity, improve mental health and fight climate change.
The concept has gained popularity after the coronavirus pandemic has brought into focus ideas around wellbeing, burnout and the work-life balance.
In December, deputy Spanish prime minister Pablo Iglesias said the idea would see a reduction in working hours in a week down to 32.

“This would then encompass a total of anywhere from 3,000 to 6,000 workers.
“The only red lines are that we want to see a true reduction of working hours.
“We also want to see no loss of salary or jobs.”
