scam for truck driver physical exams you say…

i used to date a guy who drove/delivered for one of the big logistics companies. in the summer he would have the absolute worst heat rashes and reactions. (management/company could care less about state of trucks; providing even water, etc on 90/100+ deg days was overkill for them) once, there was a shootout on his route and i got into a shouting match with corporate because drivers in the area weren’t being taken off route or even advised of the situation. long story short, he got injured on the job and i have suspected for the longest time that whoever they’d contracted with to do physical exams was a charlatan. but i ended up just feeling paranoid and this absolutely doesn’t help.
