During the summer, Workplace Dynamics surveyed 420 ProQuest employees, 81% of the workforce at the company's Ann Arbor headquarters. Employees were asked a series of questions designed to evaluate the company's direction, ability to execute its business plan, leadership, career development, work conditions, and pay and benefits. They were also asked to assign an overall score - from 0 to 99 - for the company. Responses were compared to businesses across the region to determine which firms qualified as a "Top Workplace."

ProQuest is best known for the creation of information tools and technologies that support research around the world in schools, libraries, universities and businesses. Last month, the company was ranked by InformationWeek magazine among the top 30 U.S. firms for innovative use of business technology. The workers in its Ann Arbor headquarters represent a diverse mix of jobs, including content experts of all types--from editors to librarians--as well as technologists, marketers and sales professionals. ProQuest is a mainstay of the Ann Arbor business environment and its employees are known for their community involvement.
