Illinois becomes one of the first states to pass legislation to increase its minimum wage to $15.

Illinois is following in the footsteps of other states like California and New Jersey, increasing its minimum wage, first to $9.25 per hour next year and then to $15 an hour by 2025.

The Chicago Tribune reported that Illinois’ minimum wage has been $8.25 per hour—just $1 above the federal minimum wage—since 2010, even as Chicago and Cook County have raised their minimum wages. Chicago currently has a minimum wage of $12 per hour, which is set to increase to $13 on July 1. Cook County’s $11 an hour minimum wage will increase to $12 an hour on July 1, and grow to $13 an hour the next year.

Gov. JB Pritzker, who made the $15 wage a focus of his bid for governor, signed the legislation into law on Tuesday, Feb. 19.

Illinois follows California, Massachusetts and New Jersey in raising the minimum wage. California will reach $15 an hour in 2022, Massachusetts in 2013 and New Jersey in 2024. New York is also raising its minimum wage through increases tied to inflation, The Chicago Tribune reported.
