A troubling 72% of workers age 60 or older are putting off retirement because they say they don’t have enough funds, according to a survey of 700 people that Harris Interactive conducted on behalf of CareerBuilder.

The situation appears worse for women, 76% of whom are delaying retiring, than for men, with only 68% of them putting off leaving the workforce. In addition, 50% of the respondents want to keep their jobs because of health insurance and additional benefits.

“The economy continues to cast doubt in the minds of mature workers [about] their retirement plans,” said Jason Ferrara, a senior career adviser at CareerBuilder. “Twenty-seven percent of hiring managers were approached about postponing retirements last year and were open to retaining mature workers. The key is to let your employer know sooner than later that you would like to put off your plans to leave.”
