COMMUNIST PARTY USA
People and Planet Before Profits.
The Communist Party of the USA (CPUSA) greets working people in the United States and everywhere on May Day with our heartfelt wishes that unity in struggle may bring us a better world:
This is the world dreamed of by the Martyrs of Chicago, in whose honor May First was designated as International Workers Day. This is the socialist future they fought for, and we fight for today. It is a long struggle, with many setbacks and advances, but this May Day, the signs of a new beginning are seen all over our country.
The labor movement is back, speaking with a strong, progressive and independent voice in the fight for jobs, justice, and equality. The attack on workers rights and unions has woken a sleeping giant.
The Occupy Wall Street movement and its many offspring are challenging every abuse of the capitalist system. Anti-capitalist and socialist consciousness is on the rise.
