Primary school being set up for remote learning, when that hasn't been a priority before, is a tough call.
Our yr6s are a whizz at gaming, or txt typing on a phone, but don't know how to use a PC very well. Online learning applications like Google are not free for the school, and most schools have very tight budgets (we have run out of glue sticks many a time, and many teachers will tell you they end up having the buy their own resources).
Even if there was the cash, you have to then train staff to use the software, then also create a document to explain to parents how to set their child up with an account. And deal with any support issues with both of those.
Then you'll still have some families with no way to access that learning, so will have to adapt and change anything posted so that there are printed packs ready to go out to these families.
Not sure what job you do, but imagine if your company told you it was changing how it was working, and you all had to learn new software and on top of that, you had to get your clients to download new software and learn it too.
@anyname147 Working in a school is my 2nd career, prior to that I didn't really understand how schools work either, so I don't blame you for not knowing. I do feel however if you're berating the SLT for lack of communication, then perhaps you could communicate to them yourself your enquiry as to what next steps are after the Easter Break. You did say you had emailed them, but didn't say what the response was.
I understand you're frustrated, because you want your DS to be educated whilst also allowing you to get on with your own work. Believe me when I say that your school won't be doing any of this to make your life harder, they're probably right now trying to figure out HOW to deliver education remotely that supports staff, parents and pupils. And that all takes time.
