Burnout is widespread among U.S. workers, with nearly seven in 10 reporting at least one symptom, according to a new survey by Seramount Inc.

The survey, which polled 1,000 U.S. employees working at organizations with 500 or more staff, found the problem is most acute among younger employees, with around three-quarters of millennials (77 per cent) and gen Z respondents (72 per cent) saying they’ve experienced symptoms such as exhaustion or feeling unmotivated. That compares to 62 per cent of generation X and just 38 per cent of baby boomers.

It also found more than two-thirds (68 per cent) of gen Z respondents and 61 per cent of millennials said they don’t feel supported in balancing mental-health and work, while 57 per cent of generation X and 45 per cent of baby boomers said the same. Across all age groups, only 40 per cent said their workplace provides sufficient mental-health support.

Fewer than half of gen Z workers (45 per cent) and millennials (47 per cent) rated their personal well-being as above average, compared to 56 per cent of generation X employees and 84 per cent of baby boomers.

The survey also found differences based on career level. Among senior managers, 72 per cent reported experiencing burnout, compared to 80 per cent of managers, 66 per cent of non-managers and 18 per cent of executives.
