Retiring baby boomers are already creating critical challenges in health care, and the oil and gas industries, according to a recently released study by WorldatWork, Buck Consultants, and Corporate Voices for Working Families. The study assessed the responses from more than 480 organizations in a broad cross section of industries. Regardless of industry, many companies have not planned for the exodus of mature workers. “It’s more than just a problem of not having enough bodies to replace retiring boomers; the real challenge is transferring their knowledge and talents to succeeding generations of workers,” said Buck Consultants’ spokesman James Sowers. Forty-two percent of the companies participating in the study have not identified who is responsible in their organization for knowledge transfer and knowledge management.
