Cases of burnout have been increasing at an alarming rate in recent years among millennials and Gen Zers. It’s a growing problem in today’s workplace because of trends like rising workloads, limited staff and resources and long hours.

a recent study by Mind Share Partners, Qualtrics and SAP reveals that half of millennials and 75% of Gen Zers have left a job for mental health reasons.

Another recent study, by the American Psychological Association, found the percentage of young adults experiencing certain types of mental health disorders has increased significantly in the past decade. In particular, the percentage of people dealing with suicidal thoughts increased 47 percent from 2008 to 2017.

Jean Twenge, author of iGen, a book about the effect technology has on this generation, says that “the rise of the smartphone and social media have at least something to do with it.”

But Peter Gray, a research professor at Boston College, said that it’s not social media or young people’s fractured attention spans that are causing their anxiety; it is school itself.
