In this case, a security company told workers that their 28-day entitlement to annual leave would be reduced because they were paid double for working bank or public holidays. The Northern Ireland industrial tribunal found this to be a breach of the workers' statutory right to a minimum of 28 days' annual leave.
In Kücük v Land Nordrhein-Westfalen [2012] IRLR 697 ECJ, the ECJ held that an employer's use of 13 successive fixed-term contracts over a period of 11 years was not inherently in breach of the Fixed-term Workers Directive, but that the issue of objective justification had to be assessed by the national court on the particular facts of the case.
