Older workers tend to be more unhappy in their jobs than their younger colleagues, according to a survey of more than 2,000 U.K. employees by human resource firm Robert Half U.K. One in six British workers over age 35 said they were unhappy—more than double the number for those under 35. Nearly a third of people over 55 said they didn’t feel appreciated, while 16 percent said they didn’t have friends at work.
