If the stress level at these companies seems high overall, it's because it is. In fact, 25 of the 30 companies listed have a burnout rate of 50% or higher, and 16 of the 30 have a burnout rate higher than the survey's average of 57.16%. That may seem insane, but it's par for the course in the tech industry these days. As the folks at Blind explain, you can't really explain away why Credit Karma has a higher burnout rate or Netflix has a lower one reading individual employee reviews of the places. Rather, it seems like excessive employee burnout may be an issue endemic to the tech industry at the moment.
That's not to say people aren't feeling stressed out in other industries. As the Blind survey also points out, a recent poll of HR leaders in all fields revealed that 46% of them cite employee burnout as the reason for up to half of their annual workforce turnover.
