Union leader killed in Sinaloa, Mexico
The day before May Day, Homar Salas Gastélum, the elected leader of the Union of Workers at the Service of the City of Culiacán (STASAC), was shot dead at his home in the state of Sinaloa, Mexico.
Journalist Rosario Castagnet comments: “The event does not occur in isolation. In Sinaloa, one of the historical epicenters of drug trafficking in Mexico, violence is articulated with political and economic disputes that exceed the criminal. The unions, in this scheme, function as key spaces of power, since they manage employment, resources and relations with the State. Salas’ death is part of this crossroads between local politics, informal economy and territorial control.”
El Pais also notes: “In one of his last publications, Salas had made a call for Workers’ Day on May 1 with the members of the union to march through Culiacán.”

Violence against trade unionists in Colombia
On May 1, El Colombiano reported: “Between 1971 and 2020, more than 20,0000 acts of violence against trade unionists have been recorded in Colombia. The figures were revealed by the Ombudsman’s Office within the framework of Labor Day. Among the types of violence identified are gender-based aggressions, threats against their families, sexual violence, as well as the delegitimization of their leadership and participation in union spaces.”

Journalist killed in Guatemala
On April 26, journalist Carlos Humberto Cal Ical was killed in an armed incident in the department of Alta Verapaz.
The International Federation of Journalists (FIP) and the Association of Journalists of Guatemala (APG) condemned this murder.
On May Day, PBI-Guatemala shared on social media a message from the Break the Fear Network Guatemala. That network said: “Behind every news there is effort, vocation and commitment to society. Because reporting isn’t just a job… is a public service that enables people to make decisions, demand rights and build democracy. Journalism is also dignified work. Reporting is not a crime.”
And in their International Workers’ Day message, the National Union of Rural Workers (CNTC), which is accompanied by PBI-Honduras, stated: “For us, the farmers, work is not just a daily routine; it is the sacred bond with the land and the tireless struggle for our sovereignty.”
Among the proposals made on May Day by the Confederation of Workers of Honduras (CTH), the General Central of Workers (CGT) and the United Confederation of Workers of Honduras (CUTH), the main labour federations, was the demand for justice in cases of territorial and environmental conflict linked to extractive projects.
The CNTC is affiliated with the Unified Confederation of Honduran Workers (CUTH) which is affiliated with the International Trade Union Confederation (ITUC), along with 150+ labour organizations including the Canadian Labour Congress.
