Introduction to Ley Silla

Ley Silla, officially known as the Law for the Regulation of Labor Relations in the Private Sector, has recently come into effect across the entire country. This new legislation aims to establish clear guidelines for labor relations between employers and employees in the private sector, ensuring fair working conditions and protecting workers’ rights.

Who is Ley Silla?

Ley Silla, or Law No. 24,876, was approved by the Argentine Congress in December 2021. The law is named after its primary sponsor, Argentine Senator José Mayans, who has been a strong advocate for workers’ rights throughout his political career. Senator Mayans, a member of the Frente de Todos (All for One) political coalition, has been instrumental in shaping labor laws to better protect employees and promote a more balanced relationship between employers and workers.

Key Provisions of Ley Silla

The new law introduces several significant changes, including:

  • Collective Bargaining Agreements (CBAs): Ley Silla mandates that employers negotiate in good faith with labor unions to establish CBAs, which will cover wages, working hours, and other conditions of employment.
  • Termination Clauses: The law sets stricter requirements for terminating employees, requiring just cause and providing severance pay in most cases.
  • Workplace Health and Safety: Employers are now obligated to provide a safe working environment, ensuring compliance with health and safety regulations.
  • Worker Representation: Ley Silla strengthens workers’ rights to form and join unions, as well as their right to participate in collective negotiations.

Enforcement and Penalties

Non-compliance Consequences:

Companies that fail to adhere to Ley Silla’s provisions may face penalties, including:

  • Monetary Fines: Companies can be fined between 250 and 2,500 times the Unidad de Medida y Actualización (UMA), a fluctuating economic benchmark used by the Argentine government.
  • Temporary Suspensions: In cases of repeated non-compliance, authorities may temporarily suspend a company’s operations.

Impact on Workers and Employers

Ley Silla’s implementation is expected to have a profound impact on both workers and employers:

  • Workers: The law aims to enhance job security, improve working conditions, and provide better protection against unfair dismissals.
