The why is beyond me. Trying to meet state hours in minimal days to save operating cost? Lunch pulls admin and other staff to monitor instead of doing their other routines, so they try to minimize it maybe?
15 to eat, kick them out to recess so they can clean tables for the next group.
Many don't bother to eat because the lunch line eats up their time, too.
They also yeah combine with recess time so some kids don't eat at all because they just want to energy release and play while others are just slower eaters, either way so unhealthy habit building.
Gotta get them ready for the work world where their employer will try to ignore their required (unpaid) lunch...
Where I am, parents have to pay extra to have their kids stay at school during lunch. Like we're paying a babysitter to watch them during that time. And then if we don't pay the kid isn't even allowed to stay on school grounds at lunch time.
Lunch supervision is an optional service that covers the direct cost of supervisors who set up lunchrooms, supervise students while eating lunch and on the playground, and then clean up following the lunch break. Lunch supervision costs about $1.55 per day.
Families are free to make alternative arrangements consistent with their individual circumstances, e.g., child goes home for lunch.
Lunch supervision is an annual fee that is broken down into monthly installments for ease of payment. Refunds will not be provided for occasional disruption of service due to vacation.
In my country lunch is completely different. We also only have 15 minutes to eat, but we just eat in the classroom with the teacher of the previous hour. So you have to bring your own lunch, in my school you can even buy any food. But at least I am allowed to go into the city during lunch.
