The response of a PT sup reveals at least one thing to provide an honest answer to an immediate question with the understanding, that if necessary, follow-ups are made to give a satisfactory answer to the extent the PT SUP has access to.
This is part of the responsibilities of a PT sup to maintain credibility as well as respect. Ethic standards within UPS, despite all the claims, seem to vary to a great extent. On a personal level, I have always maintained that if you can convince the lowest of your subordinates of your integrity (and that takes a lot sometimes) will be returned in a positive way. I twill take a lot of time, as the interests of PT Sups and hourlies are not always on the same track.
Throughout my entire professional life (and that includes years outside UPS), people will respond to your response in case questions are asked and you do not have an immediate answer.
I have been blessed to be exposed to situations outside my UPS experience, which very few people have. And I draw my conclusions from it and convey them to personnel at least willing to listen. What they do with this information, I cannot influence anymore.
