The Kilusang Mayo Uno (KMU) is an independent labour center promoting genuine, militant and patriotic trade unionism. It is genuine because it recognizes the struggle between labor and capital and upholds the legitimate interests of the working classmilitant because it relies on the workers collective struggle in defending trade union and democratic rights; and patriotic because it seeks to end imperialist domination and control over the Philippines.

In particular, the KMU aims to protect and promote the workers’ right to employment, a decent wage, humane working conditions, and their right to form unions, bargain collectively and to strike; defend the workers movement from yellow unionism and its reformist, economist and collaborationist tendencies; and heighten the political awareness and class consciousness of the workers through massive education, organizing and mobilizations in and out of the workplace.
