After a recent landmark legal ruling, taxpayers in Northern Ireland may be facing additional expenses to cover holiday pay for public sector workers. The Supreme Court ruled that the Police Service of Northern Ireland (PSNI) must compensate its officers and civilian employees with approximately £30 million due to inaccuracies in holiday pay calculations. The ruling determined that holiday pay should reflect an employee's normal pay, including overtime and other additional payments beyond basic salary.The case originated from a 2018 industrial tribunal ruling in favour of a group representing over 3,700 PSNI officers and civilian staff, which was upheld by the Court of Appeal in 2019. Similar cases are expected in both the public and private sectors. As a result, there may be an increase in holiday pay claims as businesses are compelled to address past or ongoing miscalculations. Public employers, who may lack substantial cash reserves, could face difficulties meeting these liabilities. The PSNI is currently considering how to cover these costs while ensuring fair compensation for its officers.
