This report presents key findings from a survey that examines employer reactions to an older white-collar worker’s request for reduced hours. The survey was funded by the Sloan Foundation, and is the first of its kind to be carried out in a nationally representative sample of establishments. It focuses on establishments with 20 or more employees, at least two of whom are white-collar and age 55 or older. It finds that while few employers have formal policies toward phased retirement, many are willing to permit phased retirement on an informal basis.
