While many Americans are happy to have jobs, most are stressed out about something at work and even more stressed than they were just a year ago.

The most common stress triggers for workers are unreasonable workloads, low pay, commutes and annoying co-workers, according to a newly released 2013 Work Stress Survey by Harris Interactive for Everest College, a trade- and career-oriented school with locations in 23 states and Canada.

“The economy has improved, but choices employers made three and four years ago are starting to impact employees,” said John Swartz, regional director of career services at Everest College. “We (employers) put a Band-Aid on issues, and now we’re paying the price. Now we’re at a breaking point, and people are frustrated and stressed out.”

In this new survey, a whopping 83 percent of American workers said they are stressed out by at least one thing at work, up sharply from 73 percent in 2012. Other stressors include lack of opportunity for advancement, fear of being laid off, poor work/life balance and working in a job that was not the person’s chosen career.

Swartz says the survey results show more than ever, top management needs to create a dialogue with employees and talk about this issue of stress.
