In a new study, researchers found that long working hours (LWH) and low psychosocial safety climate (PSC) at work were significantly associated with meeting criteria for major depressive disorder after one year.
“The results suggest that low workplace PSC and potentially long working hours (41–48; ≥55 hours/week) increase the risk of new major depression symptoms,” the researchers write.
The research was led by Amy Jane Zadow at the Centre for Workplace Excellence, University of South Australia, and published in BMJ Open. The participants were 1,084 full-time workers in Australia, randomly selected as a population-representative sample from three different Australian states.
At the start of the study, none of the participants had a diagnosis of depression. However, at the one-year follow-up, 37 (3.4%) met the criteria for depression on the PHQ-9 screening measure. The authors note that this is a small sample, which may have impacted their ability to detect the true power of the correlations between overtime work and mental health.
The PSC was strongly correlated with later depression diagnoses. A low PSC score indicates that the workplace does not prioritize employee mental health. Those whose workplaces scored low on the PSC were three times more likely than those with a high PSC to be diagnosed with depression by the one-year follow-up.
The association between depression and overtime work was more complicated. When mild depression was included, there was no relationship. However, when cases of mild depression were excluded, the association between LWH and depression became significant. This could imply that LWH influences more severe depression, but not mild depression. On the other hand, it could also imply that mild depression has too many varied causes to be captured by such a narrow investigation.
Though not directly related to depression, high work engagement increased the likelihood of working overtime hours, which was then associated with depression. The researchers write that “Overly engaged workers might tend to become workaholics ignoring early signals of depressed mood, continue working and develop major depressive disorders.”
The researchers also note that previous research on the topic has been inconclusive. However, some studies have found a significant association between LWH and depression, anxiety, sleep problems, and heart disease. In addition, some studies have found that women may be more adversely affected by overtime work. A study from Korea found that working long hours is associated with increased suicidal thinking.

Yes, work can make you depressed, angry, etc. But, the psych drugs won’t cure this problem, but, only make it worse, very much worse. What we need is to pay attention to the individual and help them discover their unique talents, skills and their purpose. I heard someone it is when you lose your purpose in life, you become most vulnerable to what ever that could harm you, including the psych drugs and therapies, etc. Each person needs to know that he or she is valuable and worthwhile. Our schools and our government don’t help people to know this. In a way, we are left on our own, but, it can be accomplished with love and patience and avoiding the drugs and therapies, etc. Thank you.
And if work, or lack of it, plus perhaps home life, social connections are
not great, then of course people won’t be happy.
Does psychiatry help with any of these things? Of course not, they in fact create
It is just a huge rotten industry.
