Mexico’s Federal Labor Law has a legal category called trabajadores de confianza, “employees of trust.” Article 9 says the category depends on the nature of the work: direction, inspection, supervision and control of a general nature, and work related to the employer’s own personal affairs within the company.
Article 185 lets the employer end the employment of such a worker “if there is a reasonable motive for loss of trust,” even when it does not match the causes for dismissal listed in Article 47.
