How common is workplace depression?

As reported by Harvard Business Review, depression causes about $44 billion worth of lost productivity each year. Although depression is the most common condition, one in five U.S. adults experiences some form of serious mental health ailment.

Many employees experiencing minor episodes of depression hesitate to seek treatment. Ignoring the symptoms, however, could result in the condition becoming a serious issue.

What are some signs of depression?

A reduction in the quality of your work performance may indicate depression. Insomnia, loss of energy or an inability to concentrate may also represent signs of its onset.

To reduce the effect of depression on your work, you could ask your manager or supervisor for a reasonable accommodation. If an adjustment to your workstation or schedule does not improve performance, you may require help from a mental health professional.

How can your health care provider help your application?

A severe and disabling condition, such as depression, requires showing the Social Security Administration that you can no longer work. Your healthcare provider can provide the supporting medical documentation you need.

If you are incapable of working at your current or most recent former position, but you can work at a less strenuous job or occupation, the SSA could deny your claim. You may, however, file an appeal within 60 days if your application results in a rejection.
