We have orders from various grocery store chains. These orders can range from 30-40 cases up to as much as 250-300 cases or more, depending on case size and weight. The employees (order selectors) have a quota based on Engineered Labor Standards. Basically smaller orders can be completed quicker, raising their overall efficiency. They earn bonus pay based on the percentage over quota they select up to as much as an additional $4.50 per hour.
Currently, the orders are placed out in a stack on the table. They take an order, scan a bar code into the system to register it as being started, then go to select the order. They are supposed to only take the next order regardless of size. At times, some of the "unscrupulous" ones will lurk around until supervision is lax, and thumb through the stack, taking an order which which possibly better benefit them, rather than the one on the top o the stack, essentially screwing their coworkers over.
The "blind box" is an attempt to remedy this. By all of the orders being placed into the box, there will be no way for them to riffle through to "cherry pick" the good ones out. They can only pull a shelf, and take what they get. Each order is placed on its individual shelf, the shelves are pulled from bottom to top. Once the shelf is removed, the order falls down to the bottom of the box, where it can be retrieved through an opening at the bottom. An order on a higher shelf, if pull prior to the shelves below it, will only drop down to the next shelf.
