In February 2017, Owens Illinois Peru unfairly dismissed José Másquez, workers’ rights secretary of the union at the company SITRA-OISA (Sindicato de Trabajadores de Owens Illinois Perú) at a key moment in the collective negotiations. SITRA-OISA requested a labour inspection, arguing that the dismissal was made on anti-union grounds. On 27 June 2017, it filed a claim for unfair dismissal.
