To address the issue of persistent unemployment, the UK Government implemented a conditional welfare scheme. Prompted by Mantouvalou's argument that the scheme forces people into exploitative work, this paper addresses the ‘pressing’ question of whether the scheme is compatible with the prohibition on ‘forced or compulsory labour’ under Article 4(2) of the European Convention on Human Rights. It is argued that, whether the scheme imposes the menace of a penalty, is involuntary, seriously exploitative or a normal civic obligation, ultimately depends on different understandings of the demands of distributive justice. Given the politically contested nature of those demands, Article 4(2) is a poor weapon to use when challenging the UK's conditional welfare scheme.
