Decide on what amount of time before your activity or shift that calls will begin. In a emergency closing or delay call department heads. Department heads call staff members. If you get no answer go to the next name on the list, keep trying the missing person. Last staff member calls department heads.
Department heads call the co-ordinator.
Avoid calling people farther up on your list because this will disrupt the chain and may cause you not to get the information you are looking for.
