Back in December, I was interviewed on Radio 5 Live about my opposition to Syrian air strikes. The interviewer clearly had doubts about my politics but also about my job, evident when she introduced me in a sceptical tone as “Heather Mendick, who describes herself on Twitter as a freelance academic”. The idea of working as a freelance academic is unfamiliar, even to many university-based academics. The most common question I get asked by them is “What do you do?” In this blog I answer that question.
