Over 500 workers at a California oil refinery are on strike. Chevron, their employer, expects to make $7.3 billion in excess profits this year. Meanwhile, the company is refusing to give workers even a basic cost of living increase.

As Bay Area living and health care expenses climb, workers at the Richmond plant demand Chevron meet the needs of their environment.

Workers seek an immediate raise of 5 percent and a 12 percent raise over the next four years.
