The production line in a bread factory is usually running at high speeds, and requires the constant removal of bread from the oven, packing and stacking of boards, and then delivering it to the next stage. This process requires constant bending, reaching and heavy lifting, which is very taxing on the body. Also, packing and stacking boards in a bakery is tiring because the amount of bread is usually large and the number of loaves that need to be handled each day is also large.

In addition to bakeries, many manufacturing and production jobs require similar operations, such as assembly lines and packaging lines.
