In 2014 were participants in the movement resulting from the Iguala Massacre, denouncing the complicity of the three levels of government in the disappearance of the normalistas. They have also been present in the struggle for political independence of trade unions, including the Telephone Operators’ Savings Bank Administrators’ Union (SNTCAT) and the Honda Mexico United Workers Union (STUHM). Since 2015, the MTS prompted a new media, La Izquierda Diario, as part of an international network of digital newspapers. In 2016, after the Political Reform of the Federal District, the MTS decided to participate in the election of the Constituent Assembly of Mexico City with an independent candidacy. Released as the Anti-capitalist 5th Formula and headed by professors Sergio Moissen and Sulem Estrada, they obtained about 11 thousand votes (6% of the people voting for independent in the electoral roll), being the first socialist candidacy in the country after decades of proscription to the anti-capitalist left. They did so again in 2018 contending for the 32nd District in the Coyoacán borough, obtaining 2,863 votes.
