TOPEKA, Kan. (AP) — The Kansas Corporation Commission says most of the agency’s classified workers have chosen to leave the state’s civil service system in exchange for taking a pay raise.

KCC said Tuesday that 81 percent of its classified workers opted to leave the civil service system for the raise.

The Topeka Capital Journal reports 76 of KCC’s 94 classified employees took a 7.5 percent salary hike, and left the classified system. The KCC, which helps regulate utilities, extended the raise offer to all its classified workers this month.

Lawmakers this past spring passed legislation later signed by Gov. Sam Brownback that requires state workers to move out of the classified system when they take voluntarily pay raises or promotions.

KCC says it approved raises for all workers who sought one.
