Oh yes, that lack of responsibility.
The only person who knows how to enter, book and run exams, train invigilators, handle a JCQ inspection potentially every day, design and maintain strict security procedures. No responsibility.
The only person who knows how to interpret the Admissions code, policies, operate multiple bespoke systems, deal with queries, ensure documents are in place for appeals, tell the head that their refusal to admit a child is illegal and get shouted at for it, follow the safeguarding rules of the (generally inept) LA, shouting and crying applicants, and get people to actually give them what they need to handle the applications. No responsibility.
The person who looks at a crying child and identifies symptoms consistent with a fracture. Spots the signs that this child isn't just having a bit of a cough, they're going into anaphylaxis, administer the EpiPen, help them use an inhaler if the parent has bothered sending one in, hold a kid's head still covered in blood for hours until the ambulance gets there whilst senior staff run around demanding that you move them because it'll upset the others to have them bleeding there and ordering someone else to get a bucket and mop and clean up that blood. No responsibility.
The person who works out that there's something more than a tummyache on the 9th visit and then goes on to find out there's a huge safeguarding disclosure.
To treat self harm cuts or have a vulnerable kid telling them if they can't stay there, they'll kill themself because there's nowhere else for them to go. No responsibility.
To turn SLT big ideas into practicalities when SLT don't have a scooby what is involved and will shout at them if there's one tiny thing not how they envisaged it because it was impossible to do it that way or because they dared to want to sit down rather than stand up for five hours on parents' evening. No responsibility.
To know that whatever goes wrong, whether it's a pure fluke, SLT idiocy, not having the correct equipment or sudden thunderstorm, SLT will move heaven and earth to blame them for it. No responsibility.
To be the one trapped with the angry parent who wants to have it out with a senior staff member whilst SLT stay in their offices. No responsibility.
To know that if they work their arses off and do everything right, somebody in SLT will use their hard work to get themselves a payrise. But the person working so bloody hard won't get one 'because there's no money'.
No responsibility. No credit. But all the blame in the world.
