All Out on May Day – the international day of struggle of the working-class!

ICOR Call for May Day 2019


The world over, the working-class movement is challenged to fight against the cross-border, intensified exploitation and oppression of the working class! Stop the rightward development of governments, the strengthening of fascist forces and outright threats of war!

In face of increasing crises and intensified rivalry, all imperialists are becoming more aggressive. The open trade war of the USA against its imperialist rivals is being fought out on the backs of the masses. A number of new, highly dangerous hotbeds of war are developing. Regional environmental catastrophes, fracking, or the emissions fraud of the car manufacturers document the threatening destruction of the foundations of human life. Today the fight for more jobs and environmental protection cannot be allowed to be played off against each other in any struggle!

US-Imperialism remains to be the strongest imperialist great power and the main warmonger. It is mainly responsible for the support of Zionist expansion and aggression in Palestine or the systematic subversion, counterrevolutionary acts and aggression against the sovereignty of Venezuela.


The correct strategy and tactics against the imperialist world system require a constant and exact analysis of the changes in the imperialist world system, a discussion in the working-class movement, and consequences must be drawn.

The industrial workers and working masses on all continents feel the consequences of a hectic and deepening competition among the imperialist monopolies. Mass layoffs in the auto industry, hiring and firing of thousands of temporary workers, strangling of labor rights and even forms of work slavery have become pressing concerns of the international proletariat.

The masses in all parts of the world see themselves challenged to rebel in combination with the search for a societal alternative. While the inhumane lack of perspective of life under imperialism increases, a new perspective is arising from the joint struggle and orientation of the broad masses of people.

We see mass protests, like the ones against the G20 summit in Argentina or before Bolsonaro’s election in Brazil. In the Middle East and Northern Africa, powerful new uprisings express the general dissatisfaction among the working class and oppressed and the lessons they have drawn from the uprisings of 2010/11. Longstanding dictators, like in Sudan and Algeria, are being overthrown.

The worldwide militant women's movement is setting an example in powerful demonstrations. It will develop revolutionary potential if it recognizes and attacks the inherent patriarchal structures of the capitalism system with its double exploitation and oppression of the masses of women. Currently the growing worldwide ecological mass movement is attracting hundreds of thousands of young people and enabling them to express their anger about capitalist exploitation of humanity and nature.



In Poland, Hungary or Germany, hundreds of thousands demonstrated against the dismantling of democratic rights and freedoms. In France the Yellow Vest movement, originally opposing fuel prices increases, swiftly gave rise to a political mass movement against the politics of the government. In many struggles, industrial workers take the lead, for example the miners in South Africa and in Ukraine with week-long strikes. Especially on May Day as the international day of struggle of the working class, socialism must be propagated as the only perspective for the future, and this must become the center of discussions!

The ruling powers react to this new, international, progressive change of mood with increased oppression, fascization of the state apparatus and the promotion of ultra-right-wing and proto-fascist forces.

Reactionary and proto-fascist regimes like in Brazil, in the Philippines, in India or Hungary demand great courage and determination from the working-class movement.

The Chinese government criminalizes the struggling Jiashi workers in Shenzen. Till today, 44 workers and Marxist students are imprisoned without charges or have even disappeared.

The trade war originating from the USA is accompanied by chauvinist propaganda and psychological war preparation. The ruling powers sometimes term one and the same reactionary measure as “punitive tariffs” and at other times “protective tariffs”. Solely the interests of the respective, nationally based monopolies are being protected.


The spreading of social-chauvinism is aimed at getting the masses to take sides with one imperialist or the other on the issues of peace, the environment or jobs, or at getting the workers to be pressed into supporting “their own” company. But the power of the workers lies in international working-class unity. After ten years of struggle against plant closure and criminalization, in September 2018 the Ssangyong workers in South Korea celebrated an inspiring victory. All dismissed workers were rehired. The Audi workers in Györ, Hungary also brought the VW capitalists to their knees with a seven-day all-out strike.

In view of the worldwide development to the right, every progressive struggle must become part of a worldwide struggle. Support the ICOR initiative for building an anti-imperialist united front against fascism and war. The workers must exercise the leadership in this front! The building of revolutionary Marxist-Leninist parties and the revolutionary world organization ICOR is the most important conclusion today for the struggle for socialism!


Workers of all countries, unite!

Workers of all countries and oppressed peoples, unite!

Long live May Day as the international day of struggle of the working-class!
