Almost one fifth of employees are working themselves into the ground.
Research from AUT conducted in December, shows 18 per cent of New Zealand workers can be classified as being burnt-out.
It also shows those workers are from 14 to 24 times more likely to have severe levels of mental health issues.
AUT Business School Professor Jarrod Haar says the results are very concerning.
He says these people are having to deal with a range of issues around anxiety, depression, lack of sleep -- and physical complaints.
Psychologist Sara Chatwin joined Simon Barnett and Phil Gifford to offer some advice.
