When you think of depressing industries, chances are childcare doesn't come to mind. But according to PsychCentral's report, mentioned on Poynteronline's Al's Morning Meeting, childcare workers had some of the highest rates of depression, in addition to elderly caregivers. Other occupations ranking high on the report include bartenders, waiters and waitresses, and cooks. Social and health-care workers ranked just behind. When broken down by gender, women were more likely to have a bout of depression, as were younger workers.

Overall, the Substance Abuse and Mental Health Services Administration says about seven percent of full-time workers have suffered through depression this year. For more statistics on the most depressing fields, check out this report from the National Survey on Drug Use and Health.
