Dannyboy,
Formal training for UPS management is as follows:
New Supervisor Orientation - HR function
Supervisor Leadership School - Manager or Division Manager level based on discussion outlines assigned
Managers Leadership School - Division Manager level
Leadership Academy - Region/Corporate or Division Manager level
People policies are also discussed at District Staff Meetings and semi yearly Career Development Meetings for UPS management moves.
District HR will attend division/dept meetings at the request of a Division or Dept Head.
I don't have an answer for your big question, I can only speak from my experiences, and not for the organization or specific areas of responsiblity.
I will say over the years, most of the UPS management I worked with had decent people skills.
Now there is the occasional management person, who likes to throw their weight around, but you have that anywhere at UPS, including hourly employees who do everything they can to buck the system, and those employees are few within the ranks of UPS hourly employees.
That's life!!
