The Workers' Left Front – Unity (, FIT-U) is an electoral alliance of four Trotskyist parties in Argentina: the Workers' Party (PO), the Socialist Workers' Party (PTS), Socialist Left (IS), and the Workers' Socialist Movement (MST). Initially founded in 2011, the alliance added MST in 2019.
After the 2023 Argentine general election, the FIT-U has five national deputies in the National Congress of Argentina: Nicolás del Caño (PTS), Christian Castillo (PTS), Myriam Bregman (PTS), Alejandro Vilca (PTS), and Romina Del Plá (PO).
The predecessor of FIT-U was the Frente de Izquierda y los Trabajadores, Anticapitalista y Socialista, which consisted of the PTS, IS and New Movement for Socialism (NMAS). It stood in the 2009 legislative elections. Attempts to include the PO in this front broke down because the PO insisted on filling the first three positions on the lists with its own members.
History

On 7 August, Liliana Olivero of IS was re-elected to the Córdoba provincial legislature, this post will be rotated with Cintia Frencia (PO) and Laura Vilches (PTS). The list won 3.12% of the vote, this was largely concentrated in the provincial capital where it won 5.45%.
They stood Jorge Altamira of the PO for president and Christian Castillo of the PTS for vice-president on 23 October.http://www.pts.org.ar/spip.php?article17502 announcement On 14 August Altamira and Castillo won 527,237 votes, 2.46%, in a primary election.http://www.fiscaldemesa.com.ar/2011/08/30/primaria-presidencial-resultados-finales/ Argentine official website (Spanish)
On 23 October 2011, they came very close to winning a national deputy in two areas. In Buenos Aires city their vote was only 0.2% short. In Buenos Aires Province their share of the vote would have entitled them to a deputy, but they fell at a second hurdle where they needed to win 3% of the number of voters on the electoral register. The Front mounted a legal challenge to this hurdle, but the courts turned them down.
The Front participated in mobilisations in June 2012.http://www.pts.org.ar/spip.php?article20779 article on June 2012 (Spanish) In 2013, it put forward proposals to limit officials' salaries.
2013 The Front contested the election for Neuquén city council on 30 June 2013. It won 5.7% of the vote, around double its vote for this election in 2011, and roughly in line with its vote in the provincial election that year.http://po.org.ar/blog/2013/07/04/una-votacion-promisoria-del-frente-de-izquierda/ PO on result of election (Spanish) Soon after it announced its candidates for the national election.http://po.org.ar/blog/2013/06/11/el-frente-de-izquierda-cerro-un-acuerdo-nacional-en-19-provincias/ PO on national candidates (Spanish)http://www.pts.org.ar/Acuerdo-de-candidaturas-nacionales-del-Frente-de-Izquierda-en-19-distritos-electorales PTS on national candidates (Spanish)
At the primary elections on 11 August 2013, the Front won over 900,000 votes, fairly close to doubling its vote compared to 2011. It increased its vote in nearly all provinces, in some provinces picking up a significant vote from virtually nowhere; an exception was Buenos Aires city where its vote was down marginally on 2011.

2014 On 29 January, the Front registered its alliance to contest the municipal election in Mendoza Province. In Mendoza, Argentina the list was headed by Macarena Escudero (PTS), a student, followed by Soledad Sosa and Andrés Elías (both PO). The PO headed the list in San Carlos, Mendoza.http://www.pts.org.ar/El-FIT-inscribio-su-alianza-para-las-elecciones-municipales-de-Mendoza-24676 announcement (Spanish)http://prensa.po.org.ar/po1302/2014/02/13/presentamos-los-candidatos-al-concejo/ (Spanish)
On 30 March, the Front received 13.5% of the vote in Mendoza city, so Macarena Escudero was elected as a councillor.
2015 The Front's first election of 2015 was local primary elections on 22 February in Mendoza. The Front came 2nd with 16% of the vote, and Andrés Elías is predicted to be elected as a city councilor.
In April, it won a second provincial deputy in Neuquén. The seats will be held by Raúl Godoy (PTS) and Patricia Jure (PO), to be followed by Angélica Lagunas (IS). It also won a councilor in the town of Andacollo for the first time.
In June, in Mendoza Province Macarena Escudero was elected as a provincial deputy, and Víctor da Vila was elected as a provincial senator.
In the presidential elections, two formulas competed in the primaries in August: one represented by Nicolas del Caño and Myriam Bregman (both from the PTS) against another composed of Jorge Altamira (PO) and Juan Carlos Giordano (IS — Socialist Left). The PTS formula won, with 375,874 votes against 356,977 of the PO+IS one, both adding up to a 3.25% of the total vote. On the main elections in October, Nestor Pitrola was elected as a national deputy for the Buenos Aires province, becoming the fourth Workers' Left Front deputy in the chamber, while the presidential formula headed by Del Caño got 812,530 votes, 3.23% of the total.:es:Elecciones presidenciales de Argentina de 2015
2019 After several weeks of meetings, the Workers' Socialist Movement (MST) agreed on June 11, 2019, to join the Front for the October general election.
2021 At the 2021 Argentine legislative election, the Front had its best performance, winning 5.91% of the vote and four seats in the national Chamber of Deputies (two in Buenos Aires Province, one each in Buenos Aires City and Jujuy Province).
Presidency of Javier Milei In 2024, member of the coalition and deputy Vanina Biasi was accused of Antisemitism by judge Daniel Rafecas on the advice of federal prosecutor Eduardo Taiano due to messages made by Biasi. The messages were described by La Nación as being "against Israel and in defense of Palestine" Biasi vehemently denied the accusations stating she's fought against Antisemitism and Racism for the past 30 years.
The coalition opposed the 2025 United States–Argentina currency swap in which the government of the United States extended $20 billion to Argentina in the form of a currency swap. They also opposed Javier Milei alignment with Israel.
In early 2026, a survey from the University of San Andrés found that 2023 presidential nominee coalition member Myriam Bregman had the lowest disapproval and highest net approval of all polled politicians. Bregman had the fourth highest approval of all figures polled. At 36.8%, she scored lower than figures such as Cristina Fernández de Kirchner and Javier Milei but above other notable figures such as Mauricio Macri and Axel Kicillof. A poll in March 2026 ahead of the 2027 Argentine general election had Myriam Bregman receiving 11.4% of the vote, if the results were to hold, they would be the best performance for the coalition, majorly improving on their 2.70% received in 2023. Christian Castillo attributed this rise to elements of the Justicialist Party shifting to the right.
