If you are involved in your Local Union, contact your fellow laborers about organizing May Day events or participating in them.
If you are not in a union but involved in your local Occupy, see how your Occupy is joining in local annual May Day festivities.
If you are involved in neither but want to get involved in a Local, I recommend you contact the Industrial Workers of the World at http://www.iww.org/.
