"A disaster such as an earthquake or hurricane creates unusual challenges for management. You and your staff may find yourselves suffering from its effects. Emotional stress, physical injury, bereavement, loss of property, and disruption of normal routines may limit the availability and energy of your work group. At the same time, the group may face new responsibilities--caring for its own members, and facilitating community recovery. Besides meeting customers' special needs for assistance following a disaster, personnel are often called on to support local authorities in providing community services. The following can help you structure your response. Much of the human suffering associated with a disaster happens after the event itself, and can be mitigated by effective management."
