Passport office staff have voted to accept a deal which will allow the recruitment of 50 temporary clerical officers.
The move will help to clear the backlog of more than 60,000 passport applications which has built up in recent months.
The result of a ballot of members of the Civil, Public and Services Union (CPSU) in passport offices in Molesworth Street, Balbriggan and Cork was released this evening.
The Labour Relations Commission proposal aims to resolve a row between the union and management at the Department of Foreign Affairs.
A system for providing passports on a priority basis is also to be put in place under the terms of the new agreement.
The CPSU and Department of Foreign Affairs both welcomed the agreement but agreed to make no further comment.
