A Belleville News-Democrat article Sunday incorrectly reported the amount of overtime paid to guards and supervisors of the Tamms Correctional Center.

The amount of overtime paid from November 2011 through Oct. 31, 2012, was $425,281, according to payroll data from the Illinois Department of Corrections.

The article Sunday, and an editorial published Tuesday, incorrectly reported the state paid at least $884,000 in overtime to correctional officers, lieutenants, sergeants and shift supervisors.

The state did pay supervisors and guards $884,000 above base salary, but the figure includes overtime and "special pay," according to IDOC.

Special pay includes double time and a half for Christmas, Thanksgiving and Labor Day and double time for nine remaining paid holidays under the state's contract with the American Federation of State, County and Municipal Workers, according to a state spokeswoman.

Correctional officers are also required to show up 15 minutes before a shift starts and are paid time and a half in "roll call'' pay.

The first sentence of Sunday's article also incorrectly stated that there were more guards than inmates at Tamms. The overall security staff at Tamms was 221 and the total number of maximum and minimum security inmates was 227, according to IDOC figures.

The maximum security section had 208 security staff members and 138 inmates, the IDOC figures show.

Eighty-nine minimum security inmates were held separately but near the main C-Max portion of the correctional center. Thirteen security staff members were assigned to minimum security.
