I love the May 4th idea but unfortunately my school district in CA (and maybe the whole state by now?) has closed schools through the end of the school year (early mid-June).
Parents in these situations will need to find much earlier “summer” child care arrangements in order to “go back to work” (if can’t work from home).
For these reasons it would be nice when school re-opening matches job-reopening. Can be handled district by district or county by county or state by state?
I would never tie American prosperity to the whims of the Teachers Unions.
