There is no better time than now to consider the labor history of the Golden State. While other states face declining union enrollment rates and the rollback of workers' rights, California unions are embracing working immigrants, and voters are protecting core worker rights. What's the difference? California has held an exceptional place in the imagination of Americans and immigrants since the Gold Rush, which saw the first of many waves of working people moving to the state to find work. From Mission to Microchip unearths the hidden stories of these people throughout California's history. The difficult task of the state's labor movement has been to overcome perceived barriers such as race, national origin, and language to unite newcomers and natives in their shared interest. As chronicled in this comprehensive history, workers have creatively used collective bargaining, politics, strikes, and varied organizing strategies to find common ground among California's diverse communities and achieve a measure of economic fairness and social justice. This is an indispensible book for students and scholars of labor history and history of the West, as well as labor activists and organizers.
