WASHINGTON – America’s lower-income workers have posted the biggest job gains since the deep 2007-09 recession — but few are bragging.

As a workforce sector, those earning $35,000 or less annually are generally pessimistic about their finances and career prospects. Many see themselves as worse off now than during the recession, a two-part Associated Press-NORC Center for Public Affairs Research survey of workers and employers shows.

The survey revealed that many people at the lowest rung in the workplace view their jobs as a dead end. Half were “not too” or “not at all” confident that their jobs would help them achieve long-term career goals. And only 41 percent of workers at the same place for more than a decade reported ever receiving a promotion.
