MADISON, Wis. (AP) – Staffing at the state Department of Corrections would increase by 50 people under provisions of Gov. Scott Walker’s budget scheduled for a vote.  The increases in staff are up for consideration Monday before the Legislature’s Joint Finance Committee.        Walker is seeking about 39 more Corrections workers to monitor a growing population of sex offenders and others required to be tracked via GPS.  He’s also asking for 18 positions to bolster the department’s information technology staffing and five people for additional mental health services at three maximum security prisons.  Walker also wants to create a new Office of Inspector General with 11 new positions to improve internal operations, lead investigations and eliminate waste, fraud and abuse.  Reductions in staff elsewhere would lead to a net of 50 new positions.
