Historic developments and an aging workforce may also
play a role.13 For example, Environmental Health Workers
as a job class had unexpected negative congruence on
knowledge of community health improvement and assessment
and the ecologic model of PH. This worker class
evolved from a sanitarian role narrowly focused on local
health code enforcement. If, as we suspect, the environmentalists
in our sample are part of an aging workforce
that has been on the job for many years, they may retain
this narrow focus. Employees trained more recently might
exhibit positive congruence on community-focused items
that are critical to contemporary PH work. Future work
may examine these data in relation to employee age,
education, and years of experience in PH. Future work
also may consider developing precise subsets of knowledge
and resources for specific occupations.
