Operations Lied on me

Are Amazon managers the dumbest managers alive? An Amazon manager lied about seeing me on my phone and tried to give me an adapt. However, she lied about the time and whether it even happened. When she saw me, my phone was facing down, and there were only three minutes left in the shift. She must have forgotten that there are cameras, lol. So, I talked to the HR lead, and he reviewed the camera footage and confirmed that I wasn't lying. The adapt was deleted, and they said she will be disciplined, lmao. I guess we’re going to have to wait and see.
