I was very lucky that, when I worked for Oxfam and other big charities, I could read lots of big reports on what influenced politicians and businesses and the general public, what campaigns worked really well, which ones didn't.
J'ai eu la chance, en travaillant pour Oxfam et d'autres organisations, de pouvoir lire beaucoup de rapports sur ce qui influençait les politiciens, les entreprises et le grand public, quelles campagnes avaient très bien marché ou non.
