In our local we have 3 buildings.We have 1 major full time senority list for all 3 buildings.Then in each building, they have there own vacation list for the people who bid into that building. My center did not post a list to work saturday,but 2 of the other centers did.Myself and another driver informed managment we wanted to work in 1 of the other buildings.(we both have more senority than most of the drivers working sat).Managment said that we couldnt work"ITS BUILDING SPECIFIC".???Then the BA OF THE UNION AGREED!??To top it off we were short a driver today,so 1 of the other centers sent up a cover driver to work with the supervisor.I just dont understand WHATS THE DIFFERENCE???Any opinions??
