You are not alone — people start hating their jobs at 35: One in six British workers over age 35 said they were unhappy in their jobs, according to a survey of more than 2,000 U.K. employees by human resource firm Robert Half UK. That’s nearly double the number of workers under the age of 35. Nearly a third of people over 55 said they didn’t feel appreciated at work, while 16% said they didn’t have work friends, Bloomberg reports. It all comes down to changing priorities and the loss of youthful naivety that comes with experience. Younger workers get excited at having a new job and have not been burned out yet, making more attractive than their older counterparts to performance-driven employers. Once they hit their 30s, however, the stress of the job — whether it is the demands of higher ranking position or disappointment at not getting there — coupled with changing life priorities such as having a family makes the job lose its luster.
