The Revolutionary Workers' Party of the Philippines, also known as the Rebolusyonaryong Partido ng Manggagawa ng Pilipinas is a communist party separated from the Communist Party of the Philippines during the Second Great Rectification Movement. The party was formed in 1995 following a split from the Communist Party due to its ideological differences like rejection of Maoism and preferring the act of insurrection over the Maoist Protracted People's War.
The Party, as well as the armed group Revolutionary Proletarian Army-Alex Boncayao Brigade, is known to be a "Rejectionist" Faction of the CPP-NPA due to its ideological differences with that said group, especially during the expulsion of 10,000 members from 1992-1993, the expulsion of former CPP member Romulo Tabara, as well as the ex-secretary of the CPP's Metro Manila-Rizal Committee Filemon "Popoy" Lagman. These events during the "Second Great Rectification Movement" Led by the CPP forced the faction to form the party in 1995. Followed by some ideological summits with the MR, CMR, Negros, Panay at Samar on October 1995, virtually rejecting the Protracted People's war.
Today, the Party continues to fight in the Parliamentary struggle. However they remain illegal both from the Government as well as from the Communist Party of the Philippines. The party is a permanent observer of the Fourth International.
