Only if you have enough trained, qualified personnel to fully staff your 3rd shift without stealing people from 1st and 2nd shift. Then you're going to need the truckers and railroads to have enough trained, qualified personnel and equipment to operate a 3rd shift without stealing people from 1st and 2nd shift.
And finally the final step, the warehouses and distribution centers those trains and trucks are going to deliver to must have trained, qualified personnel at work during the hours those 3rd shift trucks and trains will be arriving or else the ports and trucks/trains working 3rd shift is a waste.
