Quick question concerning my seniority date. Senario-I was hired as a preloader in October '14, then moved to a new building. The new building immediately needed new drivers. I cover a pick up route immediately starting in mid October. November comes around and they need Saturday air drivers. I start driving Saturday Air as well. I continue driving through mid Jan as usual. I was permanently hired on preload in Jan 15. I worked preload, drove AIR 4-5 days out of the week as well as Saturdays. My question is can your PERMANENT HIRE DATE be different from your SATURDAY AIR DATE as far as seniority and pay be concerned?
