The by-laws also indicate that: In its political action the party follows the guidelines set by a creatively developing Marxist theory and methodology, advances made by western social democracies, the positive beginnings of Soviet socialism, the achievements of the capitalist system beneficial to society, and the principles of humanitarianism, equal rights, and solidarity...

The SPF represents physical and intellectual work done on behalf of the interests of the workers in the private, public, and governmental spheres.

The SPF will seek to achieve its goals only by peaceful, political means, respecting the Constitution of Lithuania, laws, and international acts and principles that defend human rights.

The municipal elections in 2015 were more successful, as the political bloc the party participated in received 68 seats, of which 2 were delegates of SPF, including Rafael Muksinov, a member of Vilnius City Council.

On April 21, party leader Algirdas Paleckis was part of a group of activists traveling to Estonia to protest NATO's policy regarding the war in Afghanistan.

[5] In late June, SPF activists, along with anti-fascists from Latvia, were denied entry on their way to protest a meeting of veterans of the 20th Waffen Grenadier Division of the SS near the Vaivara concentration camp.

[9] Paleckis allegedly found several witnesses and ballistic assessments that seemed to indicate that there were secret snipers on the roof of the Vilnius TV centre who were shooting into the civilians.

He motivated such a decision by "diverted opinions with the party leadership", their "overestimation of the significance of rallies and underestimation of the one of participation in the election".

Other than the European refugee crisis, which they referred to as a 'involuntary immigration', the rally also highlighted "human rights abuses of the working class", "war propaganda" and "Russophobia".

The demonstration also saw the attendance of a syncretic sister organisation "The Combat", former neo-Nazi activist Žilvinas Razminas, as well as Way of Courage and right-wing populist Union of the Fighters for Lithuania.
