A recent study drew a correlation between working overtime and the development of major depression… regardless of the “stress level” of the job.  As a psychologist who works with a lot of physicians, nurses and other healthcare professionals (who often work very long hours, back-to-back shifts and rotating shifts) this is particularly relevant to my practice.  In fact, a non-scientific article listed healthcare workers among the top ten careers associated with depression.  It is particularly important for healthcare providers to be aware of the risks of mental illness and to seek appropriate treatment in a timely manner.
