Running 24/7 shifts is an impossibility, even if the manpower were there or the suppliers delivered on time predicated on the chips they receive, for the simple fact that there's not enough room on the dock to place 1,200 boxes daily awaiting for the four different carriers to pick them up before the entire process would start all over again.
Think outside the box. My company uses temporary storage containers from PODS and Pack-Rat in the parking lot when they need extra space. You can rent them by the month. They pickup when you are done. We run 3 shifts a day/ 6 days/wk for manufacturing because time=money and only using 33% of the day is inefficient. We do go down to 2 shifts when it gets slow.
If they have supply chain issues, that would explain a lot. But that is why you have 2nd and 3rd backup options ready and waiting.
Their inexperience in manufacturing is obvious.
