April 24, 2008 -- As May Day approaches, there are four things that are worth remembering:
1. For workers, May Day does not celebrate a state holiday or gifts from the state but commemorates the struggle of workers from below.
2. The initial focus of May Day was a struggle for the shorter workday.
3. The struggle for the shorter workday is not an isolated struggle but is the struggle against capitalist exploitation.
