The study by Experience Works, released on Tuesday, showed 46 percent of the 2,000 low income people over 55 years who participated needed to find work to keep their homes. Nearly half of them had been searching for work for more than a year. 'These people are at the age where they understandably thought their job-searching years were behind them,” said Cynthia Metzler, president and CEO of Experience Works. 'Bur here they are, many in their 60s, 70s and beyond, desperate to find work so they can keep a roof over their heads and food on the table.” According to the study, many of the participants had no intention of working past their 60 th birthday, but _______ after being laid off or following the death of the partner. Over a third of the participants had retired. Ninety percent of the respondents 76 years and older planned to continue working for the next five years. Huge medical bills due to a persona illness or that of a partner were also reasons for coming out of retirement, the survey found. The longest and deepest economic decline since the 1930s is making finding a job for the low-income elderly workers a difficult challenge. The Experience Works study found that 46 percent of the elderly jobseekers were sometimes forced to choose between paying rent and buying food or medication. Almost three-quarters believed their age made it harder to compete for jobs with younger workers. 'This study underscores calls for the need to create policies that remove barriers to employment for elder workers and provide additional programs and services specifically aimed at helping elder people re-enter the work force or remain working,” said Metzler. 1.
