United Socialist Workers' Party (PSTU) The United Socialist Workers' Party (PSTU) is a Brazilian far-left political party founded in 1992 that adheres to Trotskyist and Marxist traditions. The party has been active in labor disputes, student movements, and street protests, and it maintains connections with international socialist organizations, trade unions, and leftist publications. PSTU has contested municipal, state, and federal elections while emphasizing revolutionary socialism, workers' self-organization, and anti-imperialist positions.
The PSTU emerged in the early 1990s from splits and reunifications among Trotskyist tendencies linked to the Fourth International currents, tracing roots to the Socialist Workers' Party and factions stemming from the Workers' Party debates of the 1980s and 1990s. Founding activists included militants who had participated in the Diretas Já mobilizations and student campaigns influenced by events such as the fall of the Soviet Union and the Zapatista Army of National Liberation uprising. During the 1990s the PSTU engaged with unions like the Central Única dos Trabalhadores and regional movements in São Paulo and Rio de Janeiro, and later coordinated international solidarity with groups in Argentina, Bolivia, and Venezuela. The party's trajectory included legal registration, internal reorganization, and participation in coalitions during crises linked to the impeachment of Fernando Collor de Mello and the administrations of Luiz Inácio Lula da Silva.
PSTU articulates a Trotskyist program drawing on theorists such as Leon Trotsky, Karl Marx, and Rosa Luxemburg, opposing what it describes as reformism represented by the Workers' Party leadership and advocating a transitional program for workers' power. The party supports nationalizations of key sectors inspired by models debated after the October Revolution and emphasizes internationalism in line with the International Workers' League – Fourth International. On foreign policy PSTU has criticized interventions by the United States and supported self-determination for movements in Palestine, Cuba, and Venezuela. The party takes positions on social issues informed by alliances with feminist currents like Marcha das Mulheres, LGBTQ+ organizations such as Parada do Orgulho LGBT de São Paulo, and indigenous mobilizations connected to leaders from the Landless Workers' Movement (MST) and indigenous parties in the Amazon rainforest region.
PSTU organizes through local committees, municipal branches, student chapters, and trade-union cells, with a national executive elected at congresses inspired by practices of the Fourth International. Key figures in PSTU history have included national secretaries and candidates who emerged from social movement struggles, often with ties to student organizations like the National Union of Students and labor federations such as the Força Sindical. The party's internal structure emphasizes democratic centralism in debates that recall organizational disputes within historic groups like the Socialist Party of America and European Trotskyist currents. PSTU has maintained fraternal relations with international sections in Portugal, Spain, and Argentina, and participates in conferences alongside activists from the Committee for a Workers' International and other socialist internationals.
PSTU has fielded candidates in municipal, state, and federal elections, occasionally winning seats in city councils and obtaining representation in student bodies such as the National Union of Students. Electoral results have been modest compared with larger parties like the Brazilian Democratic Movement or the Workers' Party, but the party has used electoral campaigns to publicize its platform during presidential elections and municipal races in major urban centers including São Paulo and Rio de Janeiro. PSTU electoral strategy emphasizes anti-establishment messaging similar to leftist candidacies elsewhere, including tactics used by activists in the French Communist Party and radical lists in the United Kingdom.
The PSTU has been active in labor struggles, student mobilizations, housing campaigns, and anti-austerity protests, cooperating with organizations such as the Landless Workers' Movement (MST), Homeless Workers' Movement (MTST), and municipal teachers' unions in actions reminiscent of strikes in France and mass protests like the 2013 Brazilian protests. The party has supported indigenous rights campaigns in the Amazon rainforest and aligned with environmental protests against projects promoted by corporates and state-backed entities like those involved in controversies over the Itaipu Dam and extractive projects in Pará. PSTU activists have participated in international solidarity actions for migrants from Haiti, refugees from Syria, and labor disputes in Argentina.
PSTU publishes a party newspaper and pamphlets, maintaining editorial platforms that engage with international Marxist literature and debates involving journals like the International Socialist Review and pamphlets distributed at events such as festivals organized by Marcha Mundial de las Mujeres. The party operates online outlets and social media channels to disseminate analysis of events including elections in Argentina, uprisings in Chile, and labor disputes in South Africa. PSTU-affiliated periodicals have featured interviews with scholars and activists connected to institutions like the Institute for Studies of Labor and universities in São Paulo and Rio de Janeiro.
PSTU has been criticized by rival left formations including factions within the Workers' Party and centrist organizations like the Brazilian Social Democracy Party for alleged sectarianism and for tactical disagreements over united fronts during crises such as impeachment proceedings involving Fernando Collor de Mello and conflicts during the 2016 Brazilian political crisis. Critics in trade unions and academic circles compare PSTU positions unfavorably with broader-left strategies seen in debates involving the Communist Party of Brazil and international socialist parties, while supporters argue the party maintains principled opposition to neoliberal policies associated with administrations in Brasília and global institutions like the International Monetary Fund.
