It is my understanding, Siredeline010, you have and will have a job at UPS regardless of what the company may do with your particular air route or even all air routes. If there is no air route for you to run, you can either go full time when there is an opening, if you wish to do so and have the seniority, or you can go work in the building.
Over the years, I have had to endure various changes, and it helps to be flexible. If you are told you are not needed as an air driver for some period of time, ask to be given work to do in the building. That is what I have done in the past. In my case, the hub sups both needed and were grateful for an extra worker. If you should be told there is nothing for you, pursue the matter with different managers or a union person. And...I hope these words will be received in the spirit they are intended - some people have been kind of harsh with you on this forum...work on communicating your needs and thoughts clearly. On some of your posts, some separate ideas and sentences are all run together. In general, the better a communicator you are, the more seroiusly people will take you.
Please keep us posted on your situation. As my user name suggests, I am an air driver (PM), so I would be interested in any changes that come your way.
