Management and coworkers change so quickly because they expect so much. The expectations are similar to Amazon where you have to authenticated/measure/ and write details of a certain number of items per hour (sometimes 28 depending on your category) and you're tracked what you're doing every minute you're working. The biggest complaint is that hours are always cut so you'll often work closer to 32 hours, sometimes less than 30 because there's no product. In my experience, it's a high pressure job with a lot of expectation with little reward.
