Over the past couple of years top executives at IWD have been receiving salaries that are four times higher than other jobs comparable with the same position. The state may have funded over 1.8 million dollars to pay the yearly salaries of CIETC CEO Ramona Cunningham (368,000/year) and CIETC COO John Bargman (360,000/year)
