Probably goes on way more than people think.
I had a family member who’s business was embezzled from by a “trusted employee” who had been there forever.
Basically people suck and when it comes to money they really suck.
It happens in a lot small businesses. Even “Family” outfits. I have see it several times.
It is always the person you trusted the most. “Been with us eighteen years” “Just like family” and sometimes actually is family.
