Cities are not only home to around half of the global population but are also at the forefront of the transformation of jobs, skills and labour markets. Furthermore, cities play a leading role in the COVID-19 response, as the pandemic is not only accelerating megatrends such as digitalisation and automation that change the world of work, but is also challenging city economies. In London, COVID-19 has caused an unprecedented labour market shock, with several service sectors having been devastated. The crisis and its impact on employment and firms make skills development and adult learning more important than ever. London is the first major city within the OECD to introduce a comprehensive skills strategy. The report Future-Proofing Adult Learning in London, UK analyses London’s capacity to design effective adult learning programmes, which are critical for a strong and sustainable economic recovery and for preparing for the future of work. The report sheds light on major challenges facing London, especially in light of COVID-19, while also pointing to opportunities for London to design a future-ready adult learning system that responds to the impacts of the pandemic and aligns training to rapidly evolving labour market demands.
