Our schools can't call the parents, they lack the knowledge of how to do that. I know that sounds like I'm drunk, or joking, but I'm not. For 8-years, every year the girls bring home forms where we fill our contact information, and contact order (the order you call each contact). In all but one, literally one case, has the school / high school, ever, called the right number and the right person in the list.
We have called both schools, plenty of times. We have called the board plenty of times. I've had the principals read back the information, confirming it. After all of that, in one, literally one case, has either school got it right. Why does the order matter? Well, I work from home, I'm ~500m from the primary school, and 6 km from the high school, available all day. My wife works in a job she can't randomly up and leave, or answer the phone, it could be life or death, I'm not joking, and there are real sanitation / hygiene issues with her answering the phone. My in-laws can't drive, anymore, so they are only used as a last resort to play phone tag. This is not a tricky system, 4 people, 3 numbers, in the order, Dad, Mom, Grandparents. They can not get it right!
Moreover, the schools don't report things correctly. My younger daughter had back surgery in April, in June a kid threw a ball at her back. Do you think the school went into alert mode? No, they didn't even bother to email us, let alone call us, and no incident report was filled out. We only found out, once my younger daughter got home, and explained it to us. One off, meh, but it's been trips, falls, head bangs (concussion level), and nothing ever gets relaid properly. They will call my wife, except she can't answer the phone, and won't, and they know that, but they never call me.
Ignoring that shit show, should we bring up the fact you can look up information? My older daughter gets in trouble for using her phone, to look up information, why? There was recently a cannabis talk at the high school, it was offensive to the concept of truth. They didn't just make a few easy mistakes, they incorrectly defined everything, and I mean everything. I honestly think they got the material from the CBC, that's how delusional it was, and my daughter knew that, and used her phone to show the teachers, but got in trouble... why? As an example, they kept using the term THC, when they meant THCd9, they're not the same thing. I understand Health Canada makes that's error, but as an educator you have to better, they're wholly different chemicals. That's one example of many, but why not let the kids check and verify? Are you so scared you might be wrong, you have to silence information?
Outside of school, my girls still need a way to communicate with everyone, why would we limit that? You can't call us for help, because you might be on a social media? ... Okay, but social media exists regardless if you use it, so instead of hand waving and instilling pointless fear, lets understand reality still exists.
