The state of Kansas spent more than $13 million in overtime last year, and that does not include employees at universities.

Data provided by the state shows most of the overtime was paid to employees at Kansas’ mental health and correctional facilities. Those employees made $6.2 million in overtime last year.

The Topeka Capital-Journal filed an open records request for the overtime information for the 2012 calendar year.

Corrections and state hospital officials say most of the overtime is the result of an inability to fill positions at the facilities, which operate 24 hours a day.

Officials with the corrections and mental health departments say overtime was reduced last year at several of the facilities.
