The problem with slow thinking managers is that even though they are aware of the one easily fixed major problem that harms employee health and morale the most, they won’t lift a finger to resolve. There is no reason why you cannot allow employees to take a seat while performing some of the tasks. Not everything on a steer needs to be processed by a person on their feet.
I think the standing part is the least of it. They’re basically working in a freezer. Doing hard manual labor. Sitting or standing it’s an awful job that anybody that can find something better will avoid.
