Labor supporter march down Market Street Tuesday evening in San Francisco. Demonstrations were held across the Bay Area in solidarity with public employee union members in Wisconsin, whose collective bargaining rights were stripped last month by the state Legislature. Rallies were also held in Oakland, Berkeley and San Jose. A small throng of union backers in Castro Valley were seen holding signs and chanting pro-worker slogans to rush hour drivers on Castro Valley Boulevard. (Photo: Tanya Sevilla)
