When the union's inspiration through the workers' blood shall run
There can be no power greater anywhere beneath the sun;
Yet what force on earth is weaker than the feeble strength of one,
But the union makes us strong.

This old labor hymn was written by Ralph Chaplin way back in 1915 and is the unofficial anthem of the US labor movement. It's sung at labor rallies and gatherings, but with an interesting twist. Organizers often pass out songsheets because many of the assembled labor activists don't know the words.

It's a sobering and even embarrassing moment for the US labor movement which is now down to about 8% of the private sector workers. Those who romanticize organized labor based on college history classes or nostalgic folksong fests need to remember that solidarity always begins with a hope....not a certainty.

And if solidarity leads to even a small partial victory, you can bet there will have been lots of hard work, hard feelings and heartaches along the way to that ecstatic moment when the victory celebrations begin.

Suzan Erem and E. Paul Durrenberger have put together a book that tells how solidarity really works and that yes, the words Ralph Chaplin penned can become a reality even to those of us who can't remember the lyrics without a songsheet.The book is the product of years of research and writing from a team that consists of a former union organizer and an anthropologist . You couldn't ask for a better combo.
