I have worked for UPS for 20 years and took a 22.3 combo job 1/2 inside 1/2 air driver about 5 years ago. I have worked the same shift for the past 5 years and now I am told that my shift will change to the midnight shift? Can they do this? Also, am I able to bump other 22.3 employees who have less seniority? even if they are inside/inside?
Any words of wisdom is appreciated!
