California fast food workers will be paid at least $20 per hour next year under a new law signed Thursday by Gov. Gavin Newsom.

When it takes effect on April 1, fast food workers in the state will have among the highest minimum wages in the country, according to data compiled by the University of California-Berkeley Center for Labor Research and Education. The state's minimum wage for all other workers is at $15.50 per hour and is already among the highest in the nation.

Newsom's signature on Thursday reflects the power and influence of labor unions in the nation's most populous state, which have worked to organize fast food workers in an attempt to improve their wages and working conditions.
