This pretty much sums it up

I didn't get the promotion. They hired someone from outside. I saw her resume. It was impressive.
Btchface Assist. asked for some dates and times for an important meeting. She said that if the day was unavailable to
be explicit in saying the reason. My boss has an all day meeting regarding the event we're doing this summer. One of Btchface's bosses called my boss and asked about that date. Boss said fine. Btchface sent me an email saying "Your Boss is MORE than fine with that day so this is when the meeting is." I was in the room when boss said it was fine. The attitude in Btchface's email was totally unnecessary.
At least I leave at 4 today. Not for a happy reason though. Have to go make a shivah call.
