Grampy At the moment there is an air about of "Whoever reads this can take all the trouble to work out what I mean"
Free education for all was supposed to mean that everyone had the tools to undertake any job they went for. They would get literacy, numeracy, general knowledge and the ability to organise their time and skills, and after that the social mobility would be up to them - if they wanted it, they could go for it.
That acquisition of education has two parts who have to work together for it to succeed - the teacher/system and the pupil. Quite a lot of pupils now seem to believe that how much they learn is all up to the teacher. Meanwhile a lot of teachers are still suffering from the legacy of the no-grammar years.
That article shows how important basic literacy is. As it says " Few areas of the workplace are untouched by grammar in some way; even if your job doesn’t directly involve writing, chances are you’ll still need to communicate in writing with your co-workers, management, and clients or customers at some point."
