Here in SC public schools are open for classroom learning. There hasn’t been a problem. Open red states like Fla, SC, and Tx are making blue states look bad.
Years ago we had a high teacher absentee rate. My town was spending a lot on substitutes. It became an issue. A not so bright teacher wrote a letter to local paper saying your kids make us sick. That’s what’s going on with teacher unions. They hate kids.
NC schools are open also and we have Pooper Cooper in charge. We are having problems with teachers getting sick and having to quarantine for the required 10 days. Their whole classes also have to stay home 10 days. The week before Christmas, 3 schools in our district had to go totally virtual because they didn’t have enough staff to keep the schools open. The kids are doing remarkable well though. Our school has only had about 20 cases since school reopened in September. It’s the teachers getting sick that are causing the most problems with keeping schools open. This was predicted.
