Most American workers are satisfied with their jobs, but nearly two in three have strong doubts about being able to eventually stop working and retire, according to a StrategyOne survey.

The vast majority of employed Americans who were surveyed describe themselves as satisfied with their jobs (82 percent) and report they get satisfaction from their work (80 percent). About three out of four (72 percent) also said they enjoy where they work and look forward to coming to work every day.

Equally high percentages of workers said they feel respected by their bosses (83 percent) and feel their boss respects their work (82 percent). Co-workers also got high marks, with three out of four Americans (74 percent) saying their colleagues are among the best things about where they work.

But this rosy picture of the workplace belies underlying concerns, many related to the unsettled economy.

Nearly two-thirds (64 percent) believe that realistically they won't ever be able to stop working and retire, and the uncertainty of the long-term picture may help explain the divide among American workers over whether they believe they labor at a job (52 percent) or in a long-term career (48 percent).

The current economic downturn has produced a situation where almost half (46 percent) of workers have had their wages or salaries reduced over the past couple of years, and a similar segment are concerned about losing their jobs (44 percent) or having their hours cut back (48 percent).
