In 30 plus years I have have seen a gradual decline in both the quality of person(employee) from both a management and hourly perspective.
I don't mean for this to sound conceited or trying to sound like a smart ass.
In the mid to late 70's there was a recession going on and people graduating from
college were looking for work no matter what it was.
There were alot of guys in my old building who started out with UPS as part time loaders
who were going to college. And when they graduated the pay was worth staying. There were
a lot of guys I drove with who had teaching degrees, me included. And another bunch who
had 2 year associates degrees. And more than one went into management.
