‘11. Worker is a European concept. That means that it is defined by European law, through the decisions of the European Court of Justice. Member States cannot adopt their own definitions of the concept for European purposes. See Hoekstra v Bestuur der Bedrijfsvereniging voor Dertailhandel en Ambachten [1964] ECR 177. … 13. Work means the performance of services under the direction of another for remuneration. See Lawrie-Blum v Land Baden-Wurttemberg [1986] ECR 2121 , paragraph 17. The services must be in pursuit of an economic activity. See Levin v Staatssecretaris van Justitie [1982] ECR 1035 , paragraph 17. The evidence of the few jobs that the claimant had been 2001 and 2004 suggests that they satisfied these conditions. 14. The temporary nature of the jobs is relevant. In Lawrie-Blum , the Court included in its definition of work that it should be for a certain period of time. However, the Court has held that work for any given period is not essential. See Lair v Universitat Hannover [1988] ECR 3161 , paragraph 42. The Court has applied the same test whether the activity undertaken is part-time, irregular or intermittent: does it represent the pursuit of an effective and genuine economic activity? See Levin paragraph 11. Activities which are on such a small scale as to be purely marginal and ancillary do not amount to work. See Levin paragraph 17. In Raulin v Minister van Onderwijs en Wetenschappen[1992] ECR I-1027 , the work that was irregular and intermittent. It held (at paragraphs 14 and 15) that, in determining whether activities are purely marginal and ancillary, regard may be had to their irregular nature and limited duration. I consider that the same test is appropriate if the activity undertaken is temporary. The Court’s reference to the ‘very limited number of hours in a labour relationship’ shows that the test applied to temporary work.’
