CHICAGO (CBS) — The minimum wage in Chicago will rise to $12 an hour starting Sunday, under an ordinance that will raise it to $13 next summer.

In 2014, the City Council approved a measure to gradually boost the minimum wage from $8.25 an hour to $13 an hour by July 1, 2019. The current minimum wage in Chicago is $11 an hour.

In the rest of Illinois, including suburbs that opted out of Cook County’s minimum wage increase, the minimum wage is $8.25 an hour.
