If the supervisor determined that the services of an employee have been acceptable, the employee will move from probationary to regular employee status. An employee will move to regular employee status on the day following the day ending the probationary period, unless notice of extension has been given to the employee in writing prior to such time. In the event of an extension of the original probationary period, an employee will move to regular employee status on the day following the day ending the extension of the original probationary period.
