This book explores the growing phenomenon of atypical work manifested in workforce flexibility, mobility, the feminization of professional employment, and technological changes. Albert and Bradley focus on an influential group of knowledge-based employees--experts--and show the way in which they are ushering in changes in the work environment by resorting to atypical employment arrangements that are enhanced by an agency system. Case studies are developed from companies including AT&T, the Hollywood film industry, London accounting firms, and specialized agencies such as Labforce and Knowledge Net.
