There are those that should be the most trustworthy occupations, but unfortunately that sometimes attracts narcissists because if they have a job where they have people's trust they can cause more damage and they have more opportunities to try and control people.
Thank goodness ,I don't think, that happens on a regular basis, but when it does it causes a lot of problems.

Corn camera man.

hmmm idk there's a # of untrustworthy people in all occupations imo

This is a good question and honestly, i can't think of one. I was going to say mortician... but we all know some of them don't do what they're supposed to do. damn near every single job has its bad apples. i side eye just about EVERY single one. Maybe garbage men? because we have literal proof that they're doing the work?🤷🏾‍♀

ANY occupation occupied by a himan being is subject to frailties and flaws. I was GOING to say "priest", or "nun", but we have all heard THOSE horror stories.
