US vs Spain Employment Law: The Key Differences

This is the headline difference. In most US states, employment is at-will: either party can end it at any time, for almost any lawful reason or none, usually without severance. Spain does not have at-will employment. A dismissal needs a valid, justified reason, the correct procedure, and, in most cases, statutory severance.

For a US employer, this reframes the whole relationship. You cannot simply let someone go at will in Spain; you plan the exit, classify it correctly, and pay what the law requires. We cover this fully in US vs Spain termination rules.

US employment often runs on an offer letter and at-will terms. Spain expects a proper written contract that fits the Estatuto de los Trabajadores and, crucially, the collective agreement (convenio colectivo) for the sector. Convenios cover the majority of Spanish employees and set binding minimums on pay, hours and leave, whether or not the person is in a union.

This is a concept with no direct US equivalent for most employers, and missing it is a common early mistake. Our guide to Spanish employment contracts explains how the convenio shapes the deal.

Spain sets a statutory maximum of 40 hours per week averaged over the year, with caps on annual overtime and mandatory daily and weekly rest. It also requires employers to record every employee’s daily working time, a duty that applies to office and remote staff alike. US federal law, through the FLSA, focuses on minimum wage and overtime for non-exempt employees, with fewer central limits on the hours of exempt staff.

The practical effect is that a Spanish employer tracks and manages working time more formally than many US employers are used to, and cannot simply treat salaried staff as having unlimited hours.

Spain guarantees at least 30 calendar days of paid annual leave plus public holidays, along with paid family and sick leave backed by social security. The US has no federal minimum paid vacation. Spain also has strong protections against discrimination and unfair treatment, and specific rules protecting employees during pregnancy, parental leave and illness.

None of this makes Spain a difficult place to employ people; it just means the baseline of entitlements is higher and more codified than a US employer may expect. Building those entitlements in correctly is routine once you know they exist.

The takeaway is not that Spain is hard, but that it is different, and the differences are knowable. Plan for just-cause employment rather than at-will, respect the convenio, track working time, and build in the leave and protections. Do that and a Spanish hire is entirely manageable.

The simplest way to get it right without becoming an expert in Spanish law is to use an Employer of Record, which applies all of this for you as the legal employer. For the cost side of the comparison, see US vs Spain employer costs, and for the wider case, why US companies are hiring in Spain.
