The basic idea of a disaster recovery plan is to get company personnel to a recovery facility in an unaffected area. Wide-area disasters make travel arduous at best. Cost and means of transportation to the hot site facility would be determined by the number of shifts that would be run, the number of people, and how far away the hot site facility is from the company local area. Discussions with people whose companies had experienced a major disaster showed that in such situations companies might suffer as much as a 60% turnover rate in personnel. For example, after the Northridge earthquake in California many employees had little willingness to return to work. After a disaster, people are traumatized, in shock, and have trouble with basic daily activities. Family care is another issue that should be thoroughly addressed in the disaster recovery plan, so that the company would be able to ensure that most people would return to work.
