MOSCTHA was born in 1985 on the initiative of Dominican trade unionists and students and Haitian immigrants. For 20 years, it carried out intensive work in the bateyes (sugar cane plantations) and in the border regions between the Dominican Republic and Haiti. Initially, its action aimed, on the one hand, to improve the almost inhuman living conditions of Haitian workers and, on the other hand, to organise a framework favourable to the return of democracy in Haiti. Since then, MOSCTHA has continued to expand the range of its activities: legal assistance, medical consultations, environmental sanitation (sanitation and water supply), micro-credits, funeral services (via AMUTRABA), training/education and trade union activities.
