Somebody has to work the grid, otherwise you will have major problems
I am taking issue with this.
Either it is allowed, or it is not. If the halacha is that Jews can work the grid, then we would do it. If the halacha is that Jews cannot work the grid, then we will not.
You seem to think that “Somebody has to work the grid, otherwise you will have major problems” will outweigh the halacha.
Of course factors of pikuach nefesh are part of halacha, but I can assure you that chillul shabbos will never be permitted just so that you can have light in your living room.
