When a high level leader leaves a company, there's a lot of pressure associated with the selection of his or her successor. Even with so much weight placed on future leaders, many companies reveal they don't have a formal plan of action to replace their higher ups. According to a new CareerBuilder survey, nearly one-third (31 percent) of companies with more than 1,000 employees said they don't currently have a succession planning program at their organization. In addition, 50 percent of senior management (CEO, CFO, Senior VP, etc.) and 52 percent of those in a vice president position said they do not have a successor for their current role.
