In Mato Grosso do Sul, the Labor Public Ministry (MPT-MS) initiated an investigation into the Estância Terapêutica Efésios 6 clinic in Três Lagoas following a multi-agency inspection on September 9, 2026. The probe, categorized as a ‘Notícia de Fato’, aims to examine potential labor irregularities after officials reviewed internship terms, voluntary work agreements, and service contracts.

Separately, in Mato Grosso, a labor court ruled against a pregnant worker who had been dismissed by a cleaning outsourcing company. The court found that the worker had presented five falsified medical certificates to justify absences. Judge Juliano Girardello ruled that the misconduct was ‘robustly proven’, upholding the dismissal for cause and convicting the worker of bad faith litigation.
