Five exemplar job classes were selected to examine in more detail
to determine which tasks, knowledge, or resources led to agreement
or disagreement among employees. Four classes—PH Agency
Director, PH Nurse, Clerical/Administrative Assistant, and Environmental
Health Worker—were chosen because they were common
across all 19 LHDs and together comprised approximately 60% of
the national LHD workforce at the time of data collection.8 The fifth
exemplar job class, Nutritionist, at 0.5% of the workforce,8 was
chosen because the scope of work is comparatively well defined.9
