This hype about minor issues are one of the reasons why we have so many teaching jobs open and lots of primary schools can't find head teachers.
This is a minor school rule. As long as its not corporal punishment/something major, parents (and papers) need to understand the issues they cause by intervening/complaining about minor rules. Plus the negative culture that ensues.
A heads role is stressful enough without The Guardian (and parents) having an opinion. I think the best thing to do is butt out.
Do the children care and is it going to affect their overall education? Not really.
Do teachers get demoralised and ground down about minor complaints and lack for appreciation for their work and leave the profession? Yes.
An amazing friend, who works way harder than her pay cheque would imply, is a head of a primary in a very deprived area. She says she doesn't know what will happen on Monday mornings (last week a parent o/d'ed at the weekend and she had to oversee the placement of 2 half siblings). She says 80% of her time is spent sorting out problems with parents some incredibly minor. She's amazing, but stressed, you can see why she is looking to leave the profession.
Important stuff? Spending cuts. Fluidity of Curriculum. Lack of funding for special needs, teacher retention, training new teachers.
A culture of being grateful to heads and teachers, for the work they do with our children, ignoring the small stuff would help retention. If there a culture of working with them, support and respect, they might stay.
Shame on the Guardian, for the tabloid coverage.
