I sort of get your point, but point one only happens if people let it. And you know what, most parents in my experience accept they won’t get a response immediately. If not, tough. Their problem. They could email reception, yeah. But if it’s about history, or my form group, it’s coming to me regardless anyway. So may as well cut out the middle man. In ours if parents start to get awkward, you either don’t reply or push upstairs. I like email because you can do that. You talk of doctors... but you wouldn’t expect email communication with them simply as in a clinical job it’s awkward.... I do have email communication with other professionals... my financial advisor, solicitor for example when I move house... depends on nature of the job.
