According to the union's study, in the Basque Autonomous Community 53% of overtime is not paid, while in Navarre the percentage is 27%. It qualifies this situation as “labor exploitation.” They have insisted that this is a problem that persists for decades and that although laws such as the day register have been passed, data have not been reduced.

According to the study, Navarre is the area with the lowest rate in the entire state. There are 88,419 overtime hours per week, of which 23,498 have not been paid. In this sense, they have pointed out that the situation in the CAV is "even more worrying" since no more than half of the hours extras.Segare paid for APN data, in the Spanish State 419,000 workers perform unpaid overtime, which means a weekly average of 2.6 million hours, that is, 41% of the total.

CCOO says that unpaid hours generate "great economic damage". The union argues as follows: “The economic value of unpaid hours is borne by the company. Public money, such as contributions, IRPF and consumer tax, is reduced. As he explained, in addition to causing negative damage, it is a "fraud" both for society and for workers. He added that with unpaid hours more than 70,000 jobs can be created.

Faced with this, CCOO calls on companies to comply with the rules for recording working hours. In addition, they have called for the role of the Labour Inspectorate to be strengthened in order to penalise companies that fail to comply with the rules.
