I am brown and all I can say is do what you think is right. I would however, not give up that seniority. UPS has its own issues, like any other major company. You may not fly as hard at UPS, but the night stuff will take its toll on your body. Also, UPS just opened an ANC base for the 11 and 74. Good chance newhires will be sent up there, so that is also something you need to think about. Good luck.
