“So was wondering if it is possible to do something else.”
Of course it is. I know frum postal clerks, a frum mailman, several frum police officers, a frum firefighter a frum conductor for the NYC subway system, a frum engineer for NJ Transit.
“those who do other things (driving trucks, etc…).”
As Jackie Mason once said, he doesnt drive the truck, he just controls it, he works as a controller in the trucking industry.
