Position of the company at times causes effect of over staff to occur. When company is producing far below its maximum output, there would be less work for workers to perform. It is then you will see scenarios where only one shift is maintained by the company. Whose fault?.
If you don't have enough market to sell the product that you have produced, I don't think there is any need for you to still be going into massive production otherwise you're going to be having excess product to sell.
