Spain's Returning Long-Term Sick Workers Keep Their Old Terms, Lawyers Warn Employers

Employees coming back from a long spell of sick leave cannot be demoted, paid less or pushed onto a different working-time model, according to Spanish employment-law specialists cited in Spanish media reports dated 29 October 2026. A return after extended absence, the experts stress, is not a legitimate moment to trim contractual standards or to nudge staff toward leaving the company of their own accord.

Each individual case, they add, has to be weighed against the specific employment contract, the applicable collective agreement and the law in force.

Three lines employers may not cross

One labour-law specialist singled out three fundamental points that management cannot alter unilaterally once an employee is back. First, the returning worker must not be moved into a substantially different or inferior role. Second, pay and the established working-time arrangement are off limits to one-sided changes. Third, the company may not refuse a medical assessment needed to adapt the workstation ergonomically and in line with the employee's health.

Legally, tampering with salary structure or hours counts as a substantial modification of working conditions. Under Spain's Estatuto de los Trabajadores — the Workers' Statute — such measures lack binding force without a legal basis and can be challenged by affected employees through the courts.

Prevention duties and the rules on adapting the job

Denying a worker the medical examination required to tailor the workplace to their needs puts the employer in direct breach of its occupational-safety prevention obligations. The statutory anchors are Royal Legislative Decree 2/2015, which approves the Workers' Statute, and Spain's occupational risk prevention law, Ley 31/1995.

Within the Workers' Statute, Art. 39 sets the limits of functional mobility, while Art. 41 tightly conditions substantial changes to working conditions on demonstrated economic, technical, organisational or production-related grounds and on formal procedure. On the prevention side, Art. 22 requires regular health surveillance and Art. 25 mandates special protection for staff classified as particularly vulnerable because of their state of health.

What workers can claim

Where a job is unlawfully reshaped after a long illness, those affected gain substantial legal remedies, up to the maximum compensation levels. In the case of an inadmissible substantial modification, Art. 50 of the Workers' Statute lets the employee ask a court to terminate the employment relationship.

If a detrimental change is formally and properly justified, the law provides for compensation of 20 days' pay per year of service on termination, capped at 9 monthly salaries. Where the measure was imposed in breach of procedure, or infringes the employee's dignity, the financial award follows the rates set for an unfair dismissal.
