In the 1970s, Berger collaborated on three films with the Swiss Director Alain Tanner: He wrote or co-wrote La Salamandre (1971), The Middle of the World (1974), and Jonah who will be 25 in the year 2000 (1976). His major fictional work of the 1980s, the trilogy Into Their Labours (consisting of the novels Pig Earth, Once in Europa, and Lilac and Flag), treats the European peasant experience from its farming roots to contemporary economic and political displacement and urban poverty. In 1974, Berger co-founded the Writers and Readers Publishing Cooperative Ltd in London with Arnold Wesker, Lisa Appignanesi, Richard Appignanesi, Chris Searle, Glenn Thompson, Siân Williams, and others. The cooperative was active until the early 1980s.
