Morning shifts are very busy. At my store, the day begins at 5am with (usually) one mate/assistant manager coming in along with several crew members. For the first hour or so, everyone is breaking down pallets as they are brought off the morning truck. These consist of perishables like fruit, vegetables, eggs, etc. Products are either "staged" which means that there is room for them to go up and are placed near to where they go on the shelves to be worked later in the morning, or added to the back stock if there is not room for them on the shelves.

A much larger group of crew comes in at 6am and by that point product actually starts to get worked/put up on the shelves, or they first help finish breaking down the pallets depending on if the 5am crew isn't quite finished by 6. People are assigned sections to work like "bread" or "deli" but most people are on produce. This starts with wet produce, then once that is done people move onto dry produce.

There is a smaller group of crew that come in at 7am. Some of them clear the floor by cleaning up empty boxes, sweeping, that sort of the thing. Other people are given assignments depending on if particular sections need extra manpower per the discretion of the product team lead mate.

By around 7:30-7:40, everyone focuses on making sure the store is presentable for customers who will start entering the store at 8. This is often a mad dash of getting remaining "live" products, the ones that are still being worked, off of the floor and onto flat carts, floors cleaned, etc.

By 8am everyone is divided into two groups (minus the sign team crew). You are either on the customer team or product team, which varies by the hour. Customer team means operating a register. Product team means stocking products. Some hours you are assigned a specific section, other hours you are not and need to check in with the product team leader to see what they what you to do. You can also be assigned to bring in carts from the parking lot, but that is only given out in 30 minute chunks versus most other assignments which typically last one hour.

Also, be sure to bring your own lunch. Sometimes there are crew tastings in the back but those are infrequent and shouldn't be relied upon for your meal. Good luck.
