Eisenberger (psychology, Bauer College of Business) and Stinglehamber (psychology, U. Catholique de Louvain, Belgium) outline the precepts of organizational support theory, which posits that an employee's perception of personal and professional support influences their effectiveness, and its practical implementation in the business environment. They detail the foundation of the theory, examine agents of support such as managers and social networks, and consider the personal and professional outcomes of perceived organizational support on employees. Various types of perceived support and the practical implementation in diverse environments are outlined, and means to expand future understanding of the field is considered. Eisenberger and Stinglehamber draw from diverse studies featuring employees from major corporations, including those such as Wal-mart known for low levels of employee support, which they catalog in an extensive reference section.
