This schedule is only for a limited time.
During monthly "Local Salty Nation (LSN)" exercises, I spent a week arriving at the base armory at about 5 PM to arm up and stand at Guard Mount and then get posted to the base perimeter. I was relived some time after 7 AM. That's when I would clean my weapon, turn it in and drive home to my off base quarters. During that week I'd get about 6 hours of sleep per day. I did this one week out of each month for a year. You are whining about someone else having a rough, split shift for one holiday.
Quit you're whining!
How in the world can you compare retail workers to the military?!?!
