Resource Profile: Employment Status

A History of Employment Status Observation is a clinical statement about a person’s relationship to working for pay, family earnings, or training (e.g. having one or more jobs, searching for work, etc.). A person’s ODH Employment Status is independent of Job characteristics, e.g., not “full-time work,” “part-time work,” “self-employed,” because many people have more than one job.

Usage:

• Refer to this Resource Profile: Occupational Data For Health
• Examples for this Resource Profile: Observation/observation-odh-employment-status-sample
