The article reports that about 50 percent of companies interviewed in a recent study expect the departure of mature workers to present potential knowledge vulnerabilities. Lorrie Foster, director of Research Working Groups at the Conference Board says that the maturing workforce is often seen as an issue to be dealt with instead of a great opportunity to be leveraged. About one-third of the companies interviewed have conducted workforce planning studies and identified potential knowledge areas where they could be vulnerable to compensate for those vulnerabilities. Foster also said that many companies are videotaping their senior employees to get their knowledge recorded for future use or asking mature workers to write down information after project completion. The Conference Board's report titled "Managing the Mature Workforce," recommends a series of strategic ideas and actions to foster effective management of any retirement risk to the business posed by a potential exit wave of mature workers.
