ST. CHARLES TOWNSHIP – Kane County Sheriff Pat Perez violated the state’s labor law when he disciplined, threatened and suspended a court officer in retaliation for filing union grievances, according to a Friday decision by the state labor board.

Administrative Law Judge Elaine Tarver ordered the county and Perez to stop retaliating against public employees when they engage in protected union activities and to make up court officer Michael Stuckert’s financial losses, including back pay at 7 percent interest.

Perez and the county also were ordered to post notices stating they will not retaliate against employees for filing grievances and emphasizing that Stuckert will be “made whole” for financial losses. Perez also was ordered to notify the labor board in writing within 20 days of steps he has taken to comply.
