CHICAGO (AP) — A new poll shows about half of working people 50 and older plan to retire at a later date than they previously expected. The survey released Monday by the Associated Press-NORC Center for Public Affairs Research shows older Americans are embracing a revised vision of retirement. They're not just working longer but continuing to work even after retiring from their primary career. More than 80 percent of those workers say it's at least somewhat likely they will do some work for pay even after retirement. Workers 50 and older plan to retire at about 66, nearly three years later than their expectation when they were 40. Finances, health and the need for employer benefits are most likely to play a role in retirement timing.
