Can anyone help me out with this situation. I'm a 22.3 combo(irreg depot/ pm air driver.) I have 18 years of service. I went fulltime back in 2001 which put me in my classification as a 22.3 combo. Now, let say a package car driver that have 25 years decide to bid back in the building as a 22.2 inside/ inside. He work irreg depot the first half and missort slide the second half. By him biding back into the building his seniority classification change. Which started in 2005. My question to you which one of us have more seniority.
