SACRAMENTO — The state’s growing ranks of temporary and contract workers could enjoy new civil rights protections under legislation seeking to beef up California’s 40-year-old Fair Employment and Housing Act.

The omnibus bill, AB 1670, easily passed its first legislative committee hearing Tuesday morning. In addition to expanding protection against discrimination and harassment to contract workers, the bill would increase employers’ liability by broadening the definition of a supervisor and requiring greater workplace accommodation for pregnant workers or the mentally disabled.
