Sources: 2. Developments: 2. Recent judicial decisions in Spain have addressed various disputes regarding employment terminations and labor regulations. The Spanish Supreme Court upheld a ruling against Ironlock Sistemas, S.L.U., after determining the company failed to provide sufficient evidence to justify a Temporary Employment Regulation File (ERTE) that affected 122 workers. The court noted that the employer did not provide audited accounting documentation to substantiate alleged financial difficulties. In other cases, courts ruled against employers in instances of unfair dismissal. A judge in Tarragona declared the dismissal of a compliance officer at Consorci d’Aigües de Tarragona null and void, ruling the termination was retaliation for whistleblowing regarding internal irregularities. Additionally, the High Court of Justice of the Valencian Community confirmed the unfair dismissal of a Mercadona manager, finding that disparaging remarks made by the employee did not meet the legal threshold for disciplinary termination. ## Timeline ### 2026-11-07: Spanish courts rule against employers in whistleblower and criticism dismissal cases Spanish courts have ruled against Consorci d’Aigües de Tarragona and Mercadona, overturning dismissals related to whistleblower reports and internal criticism. 2 sources. https://clstr.news/cluster/spanish-courts-rule-against-employers-in-whistleblower-and-criticism-dismissal-cases ### 2026-10-23: Spanish Supreme Court rules Ironlock Sistemas ERTE unjustified Spain's Supreme Court has upheld a ruling declaring Ironlock Sistemas' ERTE unjustified, protecting the rights of 122 workers after the company failed to prove economic necessity. 3 sources. https://clstr.news/cluster/spanish-supreme-court-rules-ironlock-sistemas-erte-unjustified --- Cite as: Spanish labor law and dismissal rulings.
