Mulvey, J. (2004). Phased retirement: Aligning employer programs with worker preferences - 2004 survey report. Washington, DC: Watson Wyatt Worldwide.

"This report explores how and why workers phase and how phasing affects when workers fully retire. This information can help employers shape phased retirement programs that will enable them to more effectively manage their workforce and ensure an adequate supply of talent and experience in the years to come. To better understand the phasing process, Watson Wyatt Worldwide commissioned a telephone survey in 2003 of 1,000 individuals between the ages of 50 and 70."
