At our store, price change comes before backstock. Sometimes if price change is super massive and there's lots of interruption by guest requests, FFs, and cardboard, etc., I don't finish pulling price. I will just let the LOD know before I leave, and it's never been an issue. Often, I will check the price change estimated times at 6 pm when they come in and let the LOD know if they're projected to be huge.
I don't think that's grounds for a write-up. My TL pulled me aside for a conversation about how much work I was actually getting done at night... so I started keeping track of everything I do and writing it down. That way when they come in the next morning and see that I didn't get to any backstock, they can see that oh, StackerMistress had 20 FFs last night and had to make a bale, etc.
