This brief provides information about the Workforce Investment Act (WIA) of 1998, how it will be implemented in the greater Phoenix, Arizona, area, and the program's relevance to business. The brief also discusses the current work force development system, including information on these five areas of interest: (1) what the literature says about work force development; (2) Arizona's current work force development system; (3) an overview of the WIA; (4) what's really new in the new system; and (5) what's in it for Arizona's business community. The report concludes that research and several prominent business organizations suggest that businesses can become involved in WIA in a number of ways that benefit companies as well as society, including participating on Local Workforce Investment Boards; using the one-stop career centers to fill employment needs; opening such centers; becoming approved training providers; suggesting potential board members; providing additional funds to boards; helping design and oversee local work force development programs; and providing information to the local boards and one-stop centers (KC)
