Hartford, Conn. ? A growing number of Americans plan to work during what are traditionally retirement years because they can’t afford to stop earning a paycheck, according to a recent survey.

Nearly 70 percent of U.S. workers plan to stay in the job market full time or part time after their retirement, and 12 percent believe they will never be able to retire, according to a poll conducted jointly by the Center for Survey Research and Analysis at the University of Connecticut and the John J. Heldrich Center for Workforce Development at Rutgers University.

Those planning to work part time out of financial need jumped to 18 percent, up from 10 percent five years ago. The number of people planning to work part time to pursue interests, meanwhile, dropped to 27 percent, from 42 percent in 2000.

And those who said they would have to work full time because of economic necessity doubled in the past five years, to 6 percent.
