U.S. workers are more nervous about unemployment this summer than they were a year ago, according to analysts at Hartford Financial Services Group Inc.

The percentage of workers who said they fear losing their jobs has increased to 27%, from 11%, the analysts report in a summary of results from an online survey of 1,019 U.S. adults ages 18 to 64. Hartford commissioned the survey to investigate participants’ views on time-off and income security.

About 56% of the participants said they plan to use all of their paid time off from work this year, up from 48% in 2008, but many participants said they fear the state of the economy might force them to postpone vacations.

Other survey results:

- The participants in “Generation X” were more likely than older and younger participants to say they are delaying visits to doctors and dentists.

- About 41% of the participants said they have short-term disability insurance, and 36% said they have long-term disability insurance.
