Why have Americans, who by a clear majority approve of unions, been joining them in smaller numbers than ever before? This book answers that question by comparing the American experience with that of Canada, where approval for unions is significantly lower than in the United States, but where since the mid-1960s workers have joined organized labor to a much greater extent. Given that the two countries are outwardly so similar, what explains this paradox? This book provides a detailed comparative analysis of both countries using, among other things, a detailed survey conducted in the United States and Canada by the Ipsos-Reid polling group.
