On October 12, 2017, Governor Jerry Brown of California signed into law a state-wide ban on employer inquiries into an individual’s salary history. The new law (AB 168) will apply to all employers, including state and local governments, and will take effect on January 1, 2018. The new law continues the expansion of equal pay protection in California. California’s Equal Pay law has been on the books since 1949, requiring equal pay, regardless of gender, for equal work. It remained largely unchanged until 2016, when it was amended to require equal pay for “substantially similar” work.
