Glory
This is one of those tricky, thankless jobs where what you do for a living's totally and completely necessary, but where your day-to-day might not make you feel all that glorious. You'll be sweaty and dirty and completely exhausted by the end of every shift. Your joints will ache and it'll be all you can do not to just go home and veg out watching reruns of Mythbusters.
But without you, bags don't get to where they need to go. If you're lucky, every so often you'll get to interact with a thankful customer, track down a bag, restore a prized possession to someone, or even prevent an airport terrorist act. You never know.
