American workers said that 83 percent of them are stressed out about at least one thing at work as compared to the 73 percent in 2012.
According to NBC News only 17 percent said nothing stresses them out about work and interestingly workers 65 and up were most likely to be in this group.
"More companies are hiring, but workers are still weary and stressed out from years of a troubled economy that has brought about longer hours, layoffs and budget cuts," Swartz said.
Stress is so dangerous that the American Institute of Stress calls it "America's New Black Death."
"If black plague is what killed most people in Europe in the Middle Ages, then stress is what's killing us the most right now," said Dr. Daniel L. Kirsch, the president of the institute.
Workers stated that low pay and unreasonable workload was tied for the number one cause of stress. Following was annoying co-workers, undesired jobs, poor work-life balance, a lack of opportunity for advancement and fear of being fired or laid off.
