Overview

• Panel investigators found unlawful company interference and anti‑union discrimination at Atento’s call center that fostered a climate of fear.
• The ruling concludes Mexican authorities’ corrective steps were inadequate and failed to change workplace conditions.
• The dispute began with a November 28, 2023 petition by the STRM alleging dismissals, threats and pressure to back a rival union, with reports citing more than 30 workers fired.
• The panel conducted an on‑site verification on May 12–14, 2025, held hearings in Mexico City on May 15–16, and issued a definitive written decision on August 21.
• U.S. Trade Representative Jamieson Greer welcomed the outcome and pledged continued use of the mechanism, while labor advisor Michael Wessel said the decision was correct but highlighted weaknesses in Mexico’s enforcement.
