 Even in districts in Missouri, there's 170 something districts that already have a four-day week. They're mostly rural. Even in those, just under half of those parents actually like it. Of all Missouri parents, only 24% say they would prefer a four-day week. One of the big concerns is, what are they going to do on that fifth day for childcare and other things? And so, not only do parents not want it, the study also found a study of literature about the issue found that there are hardly any benefits and more negative than positive.
