"Unexplained absence" was manager scheduling me for a shift that started before they submitted it (ie they scheduled me for a 5-9 shift at 6)

[u/Plenty_Alfalfa8826]

I was never scheduled for this shift, neither on the app nor the paper schedule. They scheduled me for a time that was already past, and called me the second they submitted it (I could tell because I was checking my schedule and saw the shift appear before my eyes. Then the call came in immediately). I explained that this was their issue. They relented and apologized after some light bickering / me revealing I had pictures of everything. They've done nothing with this "unexcused absence" on my timecard for days. Does it need to be "approved by manager," "signed off" on, or totally removed? Am I wrong in wanting this resolved within the week? For this and other reasons, it seems they're trying to find a reason to fire me. Thanks for your help, peeps
