The ECJ has issued several key decisions about the effect of sickness on statutory holiday rights. Under these rulings, a worker continues to accrue statutory holiday under the WTD while off sick. They can choose between taking holiday while off sick or saving it until they return to work (Stringer v HM Revenue and Customs, [2009] C-520/06). Nobody can be forced to take holiday while off sick (Pereda v Madrid Movilidad SA [2009] IRLR 959).
