Yet again, I wasn't supposed to be to work until noon.
I got to the shop and nobody was there yet, so I went to the gas station, got some cash out of the ATM, bought a bottle of Gatorade, and went back to wait in the truck. A little while later, I heard Dan's truck pull up. I looked, and Joe was riding with him.
They both got out and Joe walked over to me and said "Why are you here already? You're not supposed to be here until noon."
Turns out, I was scheduled today from noon to 6PM, and nobody told me. The boss said nothing to me about it yesterday, other than, "I didn't fax the scheduled down there."
I will give them one more chance. If this happens again, I'm going to voice my opinion.
