The Department of Energy Experienced Worker Program Act directs the Secretary of Energy to establish a new program that awards grants and enters into agreements with nonprofit organizations to hire workers age 55 and older to provide technical, professional, and administrative support to the Department of Energy. The program targets experienced Americans who are not already DOE employees and aims to tap into their skills and expertise for various department missions. To protect existing workers, the bill includes safeguards requiring that the program cannot displace current DOE employees, affect their hours or benefits, fill positions where federal employees are in layoff status, interfere with existing service contracts, or convert program participants into permanent DOE employees. The legislation does not specify funding amounts or implementation timelines but establishes a framework for the Secretary of Energy to begin recruiting and deploying this older workforce through partnerships with eligible nonprofits that serve seniors.
