This SCREAMS lack of empathy for educators to me.
That "lack of efficiency" might be being spent altering plans for the dozen or more IEPs and 504s for students, talking to coaches, band directors, club sponsors, ANYONE who may can get thought to a troubled student.
Frankly it sounds like you are pretty well insulated from the realities of most people employed in education.
We have posted articles about teacher overtime, about teachers looking for exits from education.
And you efforts are to de-validate these experiences and say "I’m telling you someone isn’t being efficient."
DO BETTER.
