Unfair Labor Practices (Anti-Union Practices) in Chile

What counts as an unfair labor practice

Chilean law protects freedom of association, and the Código del Trabajo sanctions employer conduct that undermines it. These are called prácticas antisindicales when they interfere with a union, and prácticas desleales when they occur during collective bargaining. The central provisions begin at article 289 of the Labor Code, and a separate list covers unfair conduct during the bargaining process itself.

In practice the issues are rarely dramatic. A company pays a bonus only to workers who did not join a strike. A manager transfers a union organizer to a distant site. A supervisor tells new hires that joining the union will hurt their promotion chances. A subsidiary refuses to give the union the information it is entitled to. Each of these can be the basis for a complaint, and the consequences for an employer are real: fines, orders to stop the conduct and, in some cases, reinstatement and compensation for affected workers. The rules overlap with the individual protections of union officers described on our union leader protection page.

What we handle

Typical conduct that leads to complaints

The Labor Code gives examples rather than a closed list, and courts apply the principle to new situations. Conduct that has been sanctioned in Chile includes obstructing the formation or operation of a union, pressuring workers to join or leave one, offering benefits to non-members to discourage affiliation, discriminating between union and non-union staff, and interfering with a union's internal affairs. Surveillance of union leaders and changes to their duties or locations shortly after they take office are also common allegations.

On the union side, the law also sets rules for conduct by unions and workers, and an employer is not powerless: lawful discipline for misconduct that has nothing to do with organizing remains possible. The deciding factor is almost always the real reason behind the decision, and whether the employer can prove it with records created at the time.

How the complaint process works

A complaint for an anti-union practice is heard by the Juzgado de Letras del Trabajo (Labor Court) with jurisdiction over the workplace. It can be filed by the union, the affected workers, or by the Dirección del Trabajo after an inspection. A short statutory deadline applies, so delay is the first thing that weakens a case. Where the facts are strong, the court can order the practice to stop, impose fines measured in monthly tax units (UTM) and order reinstatement or other remedies.

Evidence usually includes internal emails, schedules before and after the alleged retaliation, bonus calculations, and testimony from supervisors and workers. Foreign managers sometimes assume that an informal WhatsApp message to a team is private. In a labor court it is evidence. We help clients review communications early, preserve what is relevant and prepare witnesses before hearings.
