When I got called in seniority order to go to the drivers class to go full time driving I was 2 months from 21 and was told I had to wait until I was 21 and they would let me know if they ran another "class" after my birthday. Come to find out 2 years later they did run another class, a month after I turned 21, which I was never told about. Lower seniority part timers attended the class and therefore were able to go utility driving for peak season and start their progression. Fast forward a year and I was able to take the class and currently have full time seniority over all the people who took the class after I turned 21 since they were only hired on as utility drivers not full time. I was just curious since they skipped me in seniority for the class to go utility driving and therefore I wasnt able to start my progression until 9 months later if I have any ground to fight it and possibly have my progression backdated to match theirs via the seniority violation. Any help or thoughts appreciated.
