Also on the school letter thing, if it's the letter template I have seen used before it's a standard communication. Afaik all parents get the same as the school don't want to show bias in sending different pieces to different parents. So I was told by a past principal, anyway.
Wouldn't pay it any mind, TUSLA will have no interest/ staff availability (they can barely get around to handling the chronic cases in a normal year) and no doubt there will be a huge number of kids over 20 days this year.
On another note, a friend of mine was contacted by contact tracing the other day - she is a teacher, there was a case in her class. Tracing asked whether the child had been in school on x date, she said yes. They then asked for a photo of a corrected copybook or other proof that the child had actually been in!
She was very snappy with them I think. Said that if her Masters made her good enough to teach/manage viral risk in a pandemic, her Masters made her good enough to take the roll and tell the truth.
I couldn't get over it myself but maybe I am wrong...
