Sadowski now plans to retire in about five years, but even then, he expects to do some work for pay. He notes that some of his friends without children have begun to retire, but he tries not to dwell on his shifted plans.
"For a moment, maybe, I have a twinge of, 'I wish that were me,'" he said. "But you can't live that way."
The shift in retirement expectations coincides with a growing trend of later-life work. Labor force participation of seniors fell for a half-century after the advent of Social Security, but began picking up in the late 1990s. Older adults are now the fastest-growing segment of the American workforce; people 55 and up are forecast to make up one-fourth of the civilian labor force by 2020.
That growth has paralleled a rising interest in retirements that are far more active than the old stereotype of moving to Florida, never to work again. Among those who retired, 4 percent are looking for a job and 11 percent are already working again. Those still on the job showed far greater interest in continuing to work: Some 47 percent of employed survey respondents said they are very or extremely likely to do some work for pay in retirement, and 35 percent said they are somewhat likely.
"The definition of retirement has changed," said Brad Glickman, a certified financial planner with a large number of baby-boomer clients in Chevy Chase, Md. "Now the question we ask our clients is, 'What's your job after retirement?'"
One such retiree who returned to the workforce is Clara Marion, 69, of Covington, La., a teacher who retired in 2000 and went back to work a year later. She retired again in 2007 but soon returned to part-time work because she needed the money.
When she first retired, she had about $100,000 in savings, but she has used much of that up. Her pension isn't enough to pay her bills, and she isn't eligible for Social Security. So she's back in a second-grade classroom, four days a week.
