I work 1-2 shifts per day, every day I am on the playa. I have a watch, and an alarm clock. I write down every shift on a notepad that I carry in my backpack. Every day after my shift, I check to make sure i have the next shift time correct. I use the alarm to remind me 2 hours before my shift. Since my shifts could happen at 6am, noon, 6pm or midnight - I have to know what is next. Since adapting that method, I have forgotten about any shifts.
I have a "Shift Backpack" with everything I could need on a shift pre-packed. (meds, water, coconut juice, snacks, warmer clothing, flashlight & spare batteries, etc.) I make sure to restock everything after each shift. So, when I need to go on-shift I grab & go. Yes, I move the notebook from my walk-around backpack to my shift backpack.
It really sucks to be ready & willing to work and then finding out that other people have flaked out and missed their shift. It got so bad that my dept now has sanctions against you when you miss shifts. So, don't be one of "those people"...
Hope this helps.
