Work environment

How the typical conditions of this occupation compare with 911 occupations in O*NET (very low = the lowest fifth).

Levels are relative. Most occupations involve a lot of contact with people, for example, so “very low” can still mean regular contact; the last column shows what workers actually reported.

Rankings compare typical U.S. occupation-level work conditions; individual jobs and employers vary. Data: O*NET 31.0 Work Context and BLS wages (May 2025).
