Our Door Security Team checks all the exterior doors each night to make they are locked. If a door is unlocked the team member pays close attention to why the door is unlocked, either human error or mechanical error. The team members receive a request from the scheduler every ten weeks, and at that time, they select one or more weeks that are able to volunteer. The weeks are from Sunday to Saturday. Each Friday, the team members are provided a checklist, via the computer, from the scheduler. We are always in need of more volunteers.
