NOTIFICATION FOR UNPLANNED AND PLANNED OVERTIME. After determining who is to be contacted, a telecommunications message (page) will be transmitted as notification. The message will include the relevant hours and assignment. If there is no response from the officer within five (5) minutes, a phone call will be made to the officer’s home, unless the officer provides an alternative phone number to be called. If no contact is made, move on to the next officer in line. The on-duty sergeant is responsible for the notification process. This task may be designated. The on-duty patrol sergeant may order an officer to work if he believes it is in the best interest of the division. Circumstances and demands must demonstrate this however. A detailed record of notifications will be kept on file to assist with any possible grievances filed by the employees. The Chief reserves the right to reassign personnel due to expected or unplanned absences of an illness or injury of a bargaining unit member of more than 4 weeks. Personnel so replaced will return to their shift or assignment when possible; or, in case of a sign- up occurring while the employee is off, the employee will be permitted to sign-up and take the new shift when he/she returns.
