I work that area now but have done it long enough that I'm fairly efficient at it (as in, know where everything goes and never need to scan anything that isn't transition). We're expected to zone, push autos, push truck, push repacks, backstock and help guests in 4.5 hours and I can usually finish it, but if they're throwing in things like pulling flexes for you then I don't see how they can maintain the same expectation. 🤔
Make sure they're sorting your vehicles in a smart way. I always start with diapers/wipes since they go straight to the shelf, and most days just try to keep up with that until the unload is finished when I then push furniture, and then my baby food boat(s) last. I have them separate food and formula so I can push them without having to move the vehicle around. Repacks are very last, once softlines breakout is finished.
I mostly just hope they give you time to really learn the area before punishing you for not being the most efficient at it right now. Speed comes from learning, learning takes time.
