Down here the age requirement to work at UPS is 18, the only exception is a 17 year old who has graduated from high school.
When it comes to inside employees, it seems to me that HR will hire anyone with a pulse. Then, when they quit, the supervisors are blamed that they were not trained properly. No offense intended to anyone who is overweight or who thinks they maybe, but a 300 pound middleaged house wife is not the perfect candidate to work at UPS in the package handling capacity.
