I worked a graveyard shift at a factory in college one summer because it was the only job that I could really find after weeks of looking. I definitely feel for the people who did it for a living.

That said, the companies aren't going to just stop, they'll just charge higher prices. To stop producing in the third shift, they'll need to:

    - add more daytime production lines, which means buying more floor space, possibly in a different location with new logistics to work out

    - new capex for the new lines

    - higher overhead because your newly expanded production lines are idle 30% of the time

    - higher overhead from daily startup and shutdown times

This is all for companies where it is feasible to do so. Some plants measure startup and shutdown in hours, if not days. Doing a full cycle every day would mean redesigning their entire operation, if it is even possible to do so at all.

Even places like hospitals don't exactly get to choose to just turn off all the life support and lights at night.
