Dozens of St. Paul Public Schools employees were not paid on time Friday, but school district officials aren’t saying what went wrong.

The district in a letter to employees Friday said the problem was connected to its PeopleSoft Self-Service portal, which employees use to view paycheck information and set instructions for direct deposits.

Spokeswoman Toya Stewart Downey said Friday that 35 employees were paid late and that an additional 12 were affected but were not scheduled to be paid that day.

Asked for more information Wednesday, Stewart Downey put the number of employees affected at “fewer than 100.”

The district issued paper checks Friday afternoon to employees who did not get their pay deposited, and reset passwords for all PeopleSoft users “as a precaution.”

District officials declined a request for an interview about the problem. They would not say whether the district had money stolen or whether they filed a police report.
