In 1996 California voters adopted proposition 209 which provided that “the State shall not discriminate against, or grant preferential treatment to, any individual or group on the basis of race, sex, color, ethnicity, or national origin in the operation of public employment, public education, or public contracting.” It banned affirmative action.
Today California voters consider proposition 16, to repeal that affirmative action ban. United Airlines weighed in, and they want to see affirmative action in California.
