there was a show on hulu, called Jamie Oliver's Food Revolution(2010).
in it, a British chef comes to a highschool and tells lunch ladies they can easily do 1 hour of laborious focus-heavy work.
while turning kids against the "frozen food in large trays" and "pink slime"
now, I want you to imagine the large food trays these older women were preparing before. it is obvious that the trays hold atleast five times as much food in that hour, because with 20m bake times, they can do many things at once.
the kids and famous chef and production crew (who's jobs hinge on this show) are pressuring these school lunch cooks, masters of logistics but not kitchen technique, to do pretty intense labor compared to their usual.
and then, at the end of it, after a few episodes the whole production is put at risk because it wasn't meeting the nutritional needs of the kids
