So I am at my 17th year at ups and am currently a part time bid air driver in the central states. My dilemma is that this year I have the most seniority and would be eligible for the next full time driver position. as i understand it I am currently under the ups pension plan, and if i went full time i would change to a teamster plan. My plan was to stay part time and have my 35 years in at age 59. Any one here close to part time retirement, and if so what will be there monthly pension.
