Management should actually see the value of PT to FT because people who have lasted long enough as a PT to make FT status have shown they have what it takes to persevere through all the BS they had to go through and have the "metal" needed to be a UPSer. Those who have demonstrated this then have to prove they can drive via the road test then have to be smart enough to be able to memorize all the drivel verbatim. You then factor in the background check and driving history...
In my eyes, the above combination is where I'd put my money over an off the street hire.
UPS probably has more reasons than I know but these are some reasons:
1) P/T are hired at UPS into their first real job and they have nothing to compare UPS Driver to.
They feel entitled and don't realize how good a friend/T job is at UPS.
People who have not experienced how crappy other companies are think UPS is worse than it actually is.
I have seen this myself within UPS and here on Brown Cafe.
2) UPS wanted to select qualified people off the street as drivers for consideration as Management.
This is a definite problem that has manifested itself in the last 10 years.
3) UPS would rather hire 25 year old people to begin as drivers ... for the same reason that Insurance companies charge more until a driver turns 25.
With the lack of opportunity in recent years, this is not a problem.
4) UPS likes to hire ex-military people which is contradictory to hiring P/T at 18 - 20.
Military people are disciplined and after being the military, UPS seems a "pretty OK" place to work.
Georgia opened in 1966 and when I was hired in 1973, probably 75% of management were ex-military.
5) Most Part-timers sticking around for a Driver job dropped out of college and as such, are not the type of achievers that UPS is looking for.
6) The success rate (reaches seniority) of an off-the-street hire is much higher than a P/T bid to driver.
This is a costly expense for UPS and is very "demotivating" to the package center management as well as the kicked-back employee.
The redlined in your post apply to Off-the-street hires as well.
As to "takes to persevere through all the BS they had to go through and have the "metal" needed to be a UPSer."
The pressure and drivel of a P/T job does nothing really to prepare one for the driver job except the physical conditioning.
Anyway, the driver job is more mental than physical (until one gets into their 40's when the body starts to breakdown).
