In December 2015, the National Court (Audiencia Nacional) declared that employers are obliged to record the daily work of all of their employees, meaning all regular/ordinary hours plus any overtime. Until this decision, employers believed they were only required to record overtime hours. It created a lot of uncertainty for employers, with many facing sanctions as a result of a campaign by the labor inspection to investigate and fine any companies found not to be complying with this obligation.

On 23 March 2017, the Supreme Court overturned the decision of the National Court by declaring that the obligation to register/record employees' working time is limited to overtime hours only. This is in line with the literal wording of the Spanish laws in this area and is welcome news to employers as it accords with their normal practice.
