I don't think the above post is a solution to the problem at all. It's unnecessary complication.
Your store needs to hire more flow team members, and schedule them to start at the same time. They unload the RDC truck and start stocking, then when food hits the dock a few go to unload and break down the frozen pallets. Once they start pushing, have more flow members start working the product in the frozen section. Keep going till frozen is knocked out, take meals as necessary, then get going on dairy; if there are several pallets, concentrate on doing those two at a time, if there are only a few, simultaneously get a produce or meat out there. Keep chiseling away at them till they're done.
Long story short, hire more flow team members. EVERY flow team member should know how to push food. Not everyone has to know how to cull. Two of our flow team members are dedicated to market and do the cull in the morning before food comes.
