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.
4. The struggle against capitalist exploitation is an essential part but not the only part of the struggle against capitalism.
