Pay raises and new hires were made without proper review.

In 2017, $85,000 of salary adjustments were made by six employees who were permitted to do so without any independent review. One of them “processed approximately 8,500 of these adjustments totaling $14.7 million,” the auditors said, pointing out that “similar conditions were noted in our two preceding audit reports.”

• Poor control of overtime.

In a test of overtime payments for 23 employees, none had been approved in advance as required by policy. During 2016 “these 23 employees individually were paid overtime ranging from $2,821 to $51,849, with total collective overtime payments of $392,813.”

• Overpayments of overtime.

Although identified as a problem in a prior audit, city schools had still not corrected the overtime rate paid to employees in a certain union. The result: excess payments totaling $208,000 in 2015 and 2016.
