PEORIA — It isn't $15 an hour, but OSF HealthCare is raising its minimum wage.

The Peoria-based medical group is increasing its minimum by $2 an hour, to $12, effective Feb. 24, according to a news release issued Thursday.

Sister Judith Ann Duvall, the OSF board chairwoman, stated the increase was the right thing to do for the 5 percent of employees it is expected to affect. Most of them work in food service, housekeeping, gift shops or the guest-services team.

Almost 1,150 OSF employees are expected to receive the raise.

"We believe our mission partners are called here, and we want to ensure that they are cared for," OSF CEO Bob Sehring stated in the release.

The Illinois House approved legislation Thursday that would increase the minimum wage to $15 an hour by 2025. The Senate approved the bill last week, so it now goes to Gov. JB Pritzker.

The current Illinois minimum is $8.25. That's $1 more than the federal minimum and $1 less than the minimum in Michigan, where OSF operates a medical center.

The raise is expected to cost OSF about $1.5 million, the news release stated.

In 2015, OSF increased its minimum wage to $10.
