Spanish workers on long-term medical leave are not required to return to their jobs after 18 months unless they receive an official decision from Social Security. The process, payment, and employment status all shift during this uncertain period, leaving many in limbo while authorities decide their future.
Reaching the 18-month mark on medical leave in Spain is not the end of the story for workers unable to return to their jobs. Contrary to common belief, the absence of a new medical appointment or notification does not mean an employee must go back to work. Instead, the process enters a complex phase where the rules—and the source of payments—can change while the Social Security system decides what comes next.
Under Spanish law, temporary incapacity due to illness or accident is initially granted for up to 365 days. If recovery seems possible, this period can be extended by another 180 days, bringing the total to 545 days—roughly 18 months. This applies to both common and occupational illnesses, as well as work-related or non-work-related accidents that prevent someone from performing their usual duties.
After 545 Days: Waiting for a Decision
Once the 545-day limit is reached, the right to receive the standard temporary incapacity benefit technically ends. However, the law provides for a continuation of payments until the Instituto Nacional de la Seguridad Social (INSS) issues an official decision. During this waiting period, the way workers receive their payments may shift: instead of being paid through their employer, they may start receiving direct payments from the INSS or the relevant mutual insurance provider. This transition does not require the worker to return to their job or signal a recovery.
It is crucial for employees to remain alert for any communication from the INSS or their mutual insurer. Missing a scheduled medical assessment without justification can result in the suspension or even termination of benefits. The uncertainty during this phase can be stressful, as workers have no control over the timeline for a final decision.
Three Possible Outcomes from INSS
Within 90 days of reaching the 545-day threshold, the INSS is required to review the worker's case. There are three possible outcomes: the worker may be declared fit and receive medical clearance to return to work; the INSS may initiate or resolve a permanent disability claim; or, in rare cases, the assessment may be postponed if there is a reasonable expectation of recovery with further treatment. However, the combined period of temporary incapacity and any extension cannot exceed 730 days from the original sick leave date.
Employment Status and Company Obligations
During the 90-day review period and any authorized extension, employers are no longer required to make social security contributions for the affected worker. Importantly, the employment contract does not automatically end when the 545-day period is exhausted. Companies may notify Social Security of the situation or issue a final settlement of outstanding payments, but these actions do not constitute a dismissal unless there is clear evidence of intent to terminate the contract. The Spanish Supreme Court has clarified that a severance payment or notification alone is not enough to prove a tacit dismissal.
Financial and Legal Uncertainty
For many, this period of waiting brings financial and legal uncertainty. Payments may be delayed or change in amount, and the lack of clarity about future employment status can be unsettling. As one recent case involving a long-serving self-employed worker highlights, the Spanish social security system can leave individuals in a precarious position even after decades of contributions.
Ultimately, the key for workers is to remain vigilant for official notifications and to understand that only a formal decision from the INSS determines when, or if, they must return to work. Until then, their employment relationship and benefits remain in a state of suspension, not resolution.
