Sleepless nights caused by work anxiety are taking a heavy toll on employees, according to a survey by Accountemps, a division of Robert Half International Inc. (NYSE: RHI). The survey found more than four in 10 professionals, 44%, often lose sleep over work.

Professionals in Miami most often lose sleep over work-related issues at 65%, followed by Nashville and New York at 9% and 55% respectively. Cleveland, Philadelphia and Minneapolis had the highest percentage of respondents who cited they never miss out on rest.

Professionals ages 18 to 34 more often lose sleep over work, at 57%; this compares to 45% of those ages 35 to 54 and 29% of those ages 55 and older. And 50% of male respondents said they lie awake often compared to 40% of women.

Those who lose sleep over work cited the following as the root causes:

• Overwhelmed with work volume/hours: 50%
• Can’t get a business problem out of my head: 48%
• Strained coworker relationships: 20%
• Worried I may lose my job: 18%
• My boss is a nightmare: 16%
• Other: 7%

“Work stressors can often follow you home, but try to check them at the door,” said Michael Steinitz, executive director of Accountemps. “If you have too much on your plate, schedule time with your manager to discuss possible solutions to alleviate the pressure, such as delegating work to others, adjusting deadlines or bringing in temporary help.”

Steinitz added, “employee stress can lead to lower job satisfaction and engagement and higher turnover. Managers can support their teams by maintaining open lines of communication and planning regular check-ins to discuss workload and other worries.”

The survey includes responses from more than 2,800 workers across 28 major US cities.
