Routines vary from store to store. I've seen disastrous approaches to it. It also depends on when you get your truck. Are you a super?
First, do the fresh meat cull and if you're adventurous, check dates on lunch meat. Most skip lunch meat, sadly.
Second, do the pulls, both frozen and in the cooler.
Third, work the walls. Fill any holes you can, flexing as you notice you don't have product. It may come with the truck, but as of late for us, all hope is lost until the FDC decides to send us what we need.
Fourth, if and when the truck arrives, I've found it's easier to break the pallet down, comparing what's left on the walls with what's arrived. If it's already on the wall, back stock it. If it isn't on the wall, and there's a chance it may go out, toss it on a cart or a u-boat.
In the midst of all of this, try creating a manual caf, looking for holes or items you know will become holes in the immediate future. Again, most people skip this, resulting in a fucked up looking meat department. I also, if time allows, try to research what I know I have excess of, or problematic items(pickles, I can't get in unless I zero them out, so I try to think ahead.)
Order is irrelevant, I suppose. The cull is a must, though. It's important to get outdated product off the floor and coupon short dated items to improve the chance to sell them.
Meat is probably the easiest department day to day. There are days where it sucks, like when you clean. These new chicken packages create a real fucking mess, even with liners. During my meat shifts, I try to finish as quickly as possible, then venture into another department to help out. Other food departments are understaffed, and meat is such an easy department that it seems unfair to me to spend a full day fucking about with it.
