In just one week's time, the Bay Area's public transportation system, BART, may face the second strike of the summer. Last month, a 4 1/2-day strike caused gridlock in the streets and led to long lines for buses and ferries.

The strike came to an end when two of BART's largest unions, Service Employees International Union Local 1021 and Amalgamated Transit Union Local 1555, agreed to a 30-day contract extension.

No word yet on how talks are going, but the situation does shed some interesting light on the complicated relationship between organized labor and Silicon Valley.
