Officials in Flint will review work records of former public safety administrator Barnett Jones who was holding two full-time jobs at the same time.
MLive.com reports Saturday that City Administrator Michael Brown will look at Jones' schedule.
Jones resigned Thursday after it was learned he also was chief security and integrity officer at Detroit's water department, about 70 miles away.
Brown said there is nothing yet to indicate Jones was not working full-time in Flint. Brown hired him in April. A foundation grant paid Jones' $135,000 Flint salary.
Despite a union official's call for Jones also to resign in Detroit, Water and Sewerage Department director Sue McCormick tells the Detroit Free Press that she will not ask him to step down from his $138,750 per year job.
