How far in advance of your shift did you call out? Did you use the phone? Did you talk with HR, TL, ETL? Do it verbally and document names, times, content of conversations.
I bought a T-Fal square griddle at the big T, gently cooking any meat almost permanently stains the surface. What's the secret? More thorough seasoning?
Biggest problem I had as a trainer (for a year) was many new hires didn't focus and were addicted to their phones. Most had the capacity but many didn't have the fuel and drive to learn. It was frustrating.
Alexander Graham Bell invented a device called the telephone. Accidents happen and with proper explanation the absence can be exonerated. No excuse for blatant forgetfulness.
