A Council Bluffs school district has apologized to teachers for a delay in their monthly paychecks.

The Council Bluffs Community School District sent an email Monday to teachers and substitute teachers alerting them that a payroll file for automatic deposits was not electronically submitted to the bank last week.

District spokeswoman Diane Ostrowski says the mistake was due to an error. 

The district will reimburse employees who received overdraft charges because of the delay. Employees who are customers with American National Bank received a credit for the funds to their accounts.

The error did not affect employees who receive bimonthly paychecks. That includes paraprofessionals, custodians and technicians.
