Nearly a third of employed Americas, 32%, experienced burnout at least once in the past year, according to a survey by staffing provider Yoh, a Day & Zimmermann company.

And burnout may be affecting even more workers, according to Yoh. While 32% said they felt burnout, 45% of survey respondents said they experienced indicators or contributors to burnout while not explicitly saying they suffered from burnout:

• 34% said they sacrificed their personal life (exercise, hobbies, taking care of their home) for the sake of their professional responsibilities.
• 31% said they have been required to take on additional responsibilities without decreasing their existing workload.
• 27% said they felt as if they could not take time off from work despite wanting to.
• 19% said they have been required to work more days in their company’s office instead of working from home.
• 19% said they felt overwhelmed because they had to care for a loved one at home on top of their workload.
• 16% said they felt overburdened by the number of meetings they were required to attend.
• 15% said they have been unable to consider other job opportunities because of their workload.

 “Our latest survey underscores the invisible threat job burnout poses to all companies and their employees,” Emmett McGrath, president of Yoh, said in a press release. “If left unaddressed, companies risk compromising their employees’ productivity and satisfaction — not to mention their own long-term success.”

Only 22% of workers did not report experiencing burnout or any of the contributors.

The survey included 1,201 American adults who are employed full-time or part-time and took place from Oct. 22 to Oct. 24.
