It's not a 'meme', it's a thing teachers do. They mark sets of 30 exercise books. Sometimes they also set online homework and all sorts of other exciting modern stuff, but most parents seem to want their children to be set handwritten tasks in exercise books and have them marked by teachers and most teachers find that is the best way to monitor progress. Anyway, it's not about teachers being different really - the issue applies to anyone who is working on the site and that will probably be as many non-teaching as teaching staff. And yes, of course people all over London commute to their jobs via public transport but generally less so when their jobs aren't in the centre of town. The East Dulwich Hospital site is not like working in the City or some other central location with a huge number of straightforward transport links centred on it. It is in a suburb which is not particularly easy to get to via public transport. And as a teacher at another school in the area, I can confirm that it is hugely difficult to find affordable housing in reasonable commuting distance. We lost three excellent and experienced members of staff from our department last year because they wanted family homes and that meant moving too far away to be able to travel into work each morning. We have replaced all three of them with young newly qualified staff who are living in house shares. They're great, but's not really sustainable to run a school entirely on nqts. I certainly don't think it's a good idea to have lots of people driving - I live locally and I know that the traffic is already a nightmare round there in the mornings - but it doesn't seem a very good idea to make it impossible for staff to park anywhere unless you can think of an alternative. Lay on a staff coach? Insist they all live on the 37 bus route? Recruit only the partners of bankers and lawyers who can afford to live in SE22/24?
