Cuba's president Raúl Castro led some 800,000 people in the traditional May 1 march to Havana's Plaza de la Revolución. In a brief speech, Salvador Valdés, head of the Cuban Workers' Confederation (CTC), asked workers to support the government's economic plan, which he said "will require extraordinary efforts and sacrifices" but is "vital for preserving our social system." In April President Castro called for a reduction of public spending, the elimination of subsidies and of the black market, a stimulus for agriculture, and layoffs of as many as 1 million workers, about a fifth of the workforce, from their current employment. Castro said the government would seek to create conditions so that everyone would be able to find a productive job.

As has become traditional, rival Mexican union confederations celebrated International Workers Day on May 1 with separate rallies in Mexico City's huge Zócalo plaza. The largest was organized by the independent National Workers Union (UNT), which claimed 250,000 to 300,000 participants; the local police failed to give an estimate.

In Panama, thousands of workers marched on May 1 to oppose the neoliberal economic policies of President Ricardo Martinelli's government, which they said was seeking to "take the workers back to the labor conditions of the 19th century." They protested an increase in prices of staple goods, an increase in consumption taxes, government plans for labor "reform," and a law which imposes prison sentences of up to two years for blocking traffic during protests—an effort "to stop the unions and to criminalize social protest," according to Mariano Mena, director of the National Coordinating Committee of Organized Workers.

Thousands of unionized public employees marked International Workers Day on May 1 with marches in Quito and Guayaquil, Ecuador, joined by members of socialist president Rafael Correa's PAIS Alliance (AP) party. ("PAIS" is the acronym of "Proud and Sovereign Homeland" in Spanish, and also spells the word for "country.") Unemployment in Ecuador reached 9.1% in the first quarter of 2010, up from 7.9% at the end of 2009, while underemployment among the country's 4.6 million economically active workers is officially at 51.3%.

Latin Americans generally used the traditional International Workers Day marches on May 1 this year to protest around national issues, but some also demonstrated their support for immigrants in the US—where tens of thousands of immigrants and supporters were marching against anti-immigrant measures and laws.

On April 20 Uruguayan criminal judge Juan Carlos Fernández Lecchini handed down a 20-year prison sentence to Juan Carlos Blanco--foreign relations minister from 1973 to 1976, at the beginning of a 1973-1985 military dictatorship—for "especially aggravated homicide" in the case of the schoolteacher Elena Quinteros. With the judge's decision, all the principal figures accused of human rights violations during the dictatorship have received prison sentences, although some face additional charges. Former dictator Juan Bordaberry (1973-1976) has been sentenced to 30 years in prison, former dictator Gregorio ("Goyo") Alvarez (1981-1985) to 25 years, and eight other former officials to 20-25 years for homicides, kidnappings and forced disappearances.

The Haitian government decided on April 22 to declare a three-week moratorium on forced evictions of homeless Port-au-Prince residents from improvised encampments at schools and other private property where they have been living since a Jan. 12 earthquake devastated much of southern Haiti. The government made the decision because "there are a lot of tensions," Edmond Mulet, a Guatemalan diplomat and the acting head of the United Nations Stabilization Mission in Haiti (MINUSTAH), said at a press conference later on April 22. "There are pupils who want to return to their schools to continue their studies; there are displaced people who are installed in the schools," Mulet explained. "Well, instead of having confrontations, a moratorium has been established." (Radio Métropole, Haiti, April 23 from AFP)

On April 22 the French nongovernmental organization Doctors of the World (MdM) released a report on the condition of women in Guatemalan maquiladoras in the apparel and food processing industries. "The job is unstable and badly paid, the work is dangerous for health, there is psychological and sexual harassment, insults, physical abuse, unjustified firings and interminable workdays," according to the report, based on interviews in 2006-2009 with 530 women working in 16 factories in Chimaltenango and Sacatepéquez departments in western Guatemala.
