By TOM RAUM and JENNIFER AGIESTAWASHINGTON (AP) â¿¿ While lower-wage American workers have accounted for the lion's share of the jobs created since the 2007-2009 Great Recession, a new survey shows that they are also among the most pessimistic about their future career prospects, their job security and their finances. The two-part Associated Press-NORC Center for Public Affairs Research survey of both employers and employees found high levels of anxiety among those earning $35,000 annually or less. Many of these workers say they're worse off now than they were before or during the recession. And there's no question that workers see the world differently than do their bosses. Seventy-two percent of employers at big companies and 58 percent at smaller ones say there is a "great deal" or "some" opportunity for worker advancement. But, asked the same question, 67 percent of all low-wage workers said they saw "a little" or "no opportunity" at their jobs for advancement. The survey revealed that many people on 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. Yet 44 percent of employers surveyed said it's hard to recruit people with appropriate skills or experiences to do lower-wage jobs, particularly in manufacturing (54 percent). And while 88 percent of employers said they were investing in training and education for employee advancement, awareness and use of such programs among the lower-wage workers was only modest. Although President Barack Obama made it a national goal to "equip our citizens with the skills and training" to compete for good jobs, the survey shows a U.S. workforce that has grown increasingly polarized â¿¿ between the haves and the have-nots and between employers and their employees.
