We are talking about teachers not policemen or firefighters, They work only 180 days a year, six hours a day including lunch, yet they earn more then police officers who work 6 days a week 12 months a year for 8-10 hour shifts sometimes at night or weekends and holidays.
now of coures we need to pay them a deacent wage if we want to have good teachers but they get way more then teachers in private schools who have much higher demands. (I’m not talking about yeshivos, they pay extreamly low with six days a week some of them 12 months a year with ZERO benefits).
