Recent discussions about working hours in Spain have gained attention. According to regulations from Spain’s Ministry of Labour, any arrangement exceeding legal working hours will face strict penalties. It is crucial for both employers and employees to have a clear understanding of these legal boundaries.
Legal Working Hours and Overtime Definition
Article 34.1 of Spain’s Workers’ Statute (Estatuto de los Trabajadores) clearly states that the maximum legal working time for a full-time job is an average of 40 hours per week, calculated on an annual basis. Any time worked beyond this standard is considered overtime.
For example, a common schedule of ‘8 hours a day, 6 days a week’ totals 48 hours, resulting in 8 hours of overtime each week. According to Article 35.4 of the same statute, the annual legal limit for overtime is 80 hours. At this rate, an employee would reach the annual overtime limit in just 10 weeks, making the continuation of such a work pattern a serious violation of labor law.

The Voluntary Nature of Overtime
Spanish law emphasizes that overtime must generally be voluntary for the employee, unless otherwise specified in a collective bargaining agreement or an individual employment contract. The only exception for mandatory overtime is in cases of force majeure, such as preventing or repairing disasters and other urgent, extraordinary incidents. Increased production demands, a surge in orders, or organizational issues within the company are not valid reasons to compel employees to work overtime. Unilaterally forcing overtime is a violation of employee rights.
Penalties for Violations and Employee Compensation
According to the Law on Infractions and Sanctions in the Social Order (LISOS), exceeding the legal overtime limits or failing to provide proper compensation for it is classified as a serious infraction. The Spanish Labour and Social Security Inspectorate (ITSS) is authorized to impose fines ranging from €751 to €7,500 for such offenses. The specific fine amount is determined based on the severity of the violation, its impact on employees, and the number of workers affected.
In addition to administrative fines, the company must compensate the employee. There are two options for compensation: either by providing an equivalent amount of paid time off in lieu within four months of the overtime being worked, or by paying for the overtime hours. The overtime pay rate must be at least 175% of the normal hourly wage (an increase of 75%).
The Importance of Time Tracking and How to Defend Your Rights
Whether a company maintains proper time records plays a decisive role in labor disputes. Based on precedents from the Spanish Supreme Court, if a company cannot provide reliable attendance records to prove the actual hours worked, the principle of ‘reversal of the burden of proof’ applies. This means the employee’s claimed hours are presumed to be accurate, and it is up to the company to prove otherwise.
If you are facing overtime violations or other infringements of your rights, you have the right to file a report with the Labour Inspectorate (ITSS) or to bring a lawsuit directly to the Social Courts (Juzgados de lo Social). It is worth noting that for claims under €2,000, an employee can file a lawsuit without hiring a lawyer. Furthermore, when ordering an employer to pay back wages, courts often add a 10% late payment penalty interest to further protect the worker’s legal rights.
