According to a survey by the American Psychology Association released this morning, one-third of American employees experience chronic stress at work. 

Top contributing factors are a roundup of the usual suspects: low salaries, lack of opportunity for advancement, and heavy workloads. But stress doesn’t hit all demographics equally: women and Millennials (age 18-33) reported higher stress levels than the national average.

Of the 1,501 surveyed adults residing in the U.S. who are employed full-time, part-time or self-employed, 54 percent believe they receive adequate salaries for the work they do, only 39 percent saw enough opportunities for internal promotions, while only 51 percent feel valued at work.

For women in the workplace, the numbers are even worse. In every category, women reported feeling less appreciated than their male coworkers: less valued (48 percent of women versus 54 percent of men), less satisfied with their salaries (43 percent versus 48 percent), and less likely to agree with the statement “my employer provides sufficient opportunities for internal career advancement” (35 percent versus 43 percent).

All these factors add up; unsurprisingly, women are more stressed than men at work (37 percent versus 33 percent).

Young people are feeling the burn as well. In another survey released last month, respondents between the ages of 18 and 30 reported an average stress level of 5.4 out of ten (significantly higher than the national average, a still pretty stressed out 4.9).
