The public service Pension-related Deduction (PRD) was introduced in March 2009 under the Financial Emergency Measures in the Public Interest Act 2009. PRD is a progressively structured multi-band reduction imposed on the remuneration of public servants who are members of a public service pension scheme or have entitlement to benefit under such a scheme or who have an analogous arrangement. The deduction is calculated by reference to remuneration. Remuneration is defined at section 1 of the Act as emoluments to which Chapter 4 of Part 42 of the Taxes Consolidation Act 1997 applies or is applied and payable by or on behalf of a public service body to a public servant for his or her services as a public servant. The PRD is not a pension contribution and does not confer pension entitlements. There is no relationship between the level of PRD payable and the level of potential public service pension benefit.
I have no information on the specific employment circumstances of the individual worker in question. Public Service employers are required to implement the Pension-related Deduction strictly in accordance with the terms of the Financial Emergency Measures in the Public Interest Act 2009.
