"Unpaid overtime is an endemic fraud in our society." A study prepared by the Comissions Obreres de Catalunya (CCOO) trade union quantifies the volume of extra hours worked by Catalans. It also points to a sharp increase in recent years: while in 2019 workers put in an average of 791,000 overtime hours per week, in the first quarter of this year the volume has risen to 1.02 million, representing an increase of 29.3%.
