SINACTRAHO (Spanish: Sindicato Nacional de Trabajadores y Trabajadoras del Hogar; the National Union of Domestic Workers) is a Mexican labor organization founded in 2015 with the goal of protecting the rights of domestic workers.

[1] It is the first legally established union in Mexico that focuses its activities on domestic work.

[2][3] Among its founders is the Mexican social activist Marcelina Bautista, a domestic worker since she was 14 years old.

[1][5] The organization was created in close collaboration with the Centro de Apoyo y Capacitación para Empleadas del Hogar (CACEH), which since 2000 has functioned as a space for education and personal development for women employed as domestic workers.

[9] Since 2018, when the Supreme Court of Justice of the Nation failed to enforce the right of domestic workers to participate in the social security system, SINACTRAHO has assisted workers in this sector and their employers in navigating the social security process.
