(Case C-624/19)

Watford Employment Tribunal (United Kingdom)

Questions referred

Is Article 157 of the Treaty on the Functioning of the European Union (TFEU) directly effective in claims made on the basis that claimants are performing work of equal value to their comparators?

If the answer to question 1 is no, is the single source test for comparability in Article 157 distinct from the question of equal value, and if so, does that test have direct effect?
