The fix for this crap is simple.
Take attendance while the kiddies are playing hooky.
Anyone not in the class where they’re supposed to be, gets a letter mailed to their home of record explaining exactly why that kid is now either home schooled or welcome to attempt to sign up at another school district.
Any teachers playing at the walkout game gets fired.
And, the school board takes the time and effort to have everyone at the district level replaced.
No. Home educators don’t want these rejects in our ranks.
