Spain’s recently approved labor reform takes effect today with a 90% surcharge for work performed on Sundays. This new regulation impacts businesses and employees, altering the cost of operating and working on the traditionally day of rest. The surcharge is a key component of the labor reform aimed at improving working conditions and addressing issues of overwork. Initially set at 90%, the penalty will increase to 100% in 2027. The measure seeks to discourage excessive Sunday work, promoting a better work-life balance. This change is anticipated to spark debate regarding its economic impact on various sectors, particularly retail and tourism. The reform was reported on by La Silla Vacía.
