An ‘establishment’ is the entity to which a worker is assigned:
Following the decision in the ‘Woolworths case’ (USDAW and anor v WW Realisation 1 Ltd and ors) that an establishment is the entity to which a worker is assigned, the ECJ has now handed down decisions in Lyttle and Cañas. In Lyttle, the ECJ confirmed that, as in the Woolworths case, ‘establishment’ means the entity to which workers are assigned to perform their duties. Cañas turned on Spanish legislation so has no direct relevance to the UK.
