The Psychiatric Nurses Association has voted by a narrow majority in favour of the settlement proposals which brought an end to the recent nurses' dispute.
The 6,500-strong union voted by 53% to 47% in favour of accepting the proposals put forward by the National Implementation Body which brought an end to the recent seven-week long nurses' work-to-rule.
The proposals will see the working week for nurses cut to 37.5 hours by June next year.
An independent commission will examine how and when a 35-hour week can be achieved.
The nurses' claim for a 10.6% pay rise will be dealt with through the benchmarking process.
The result of today's ballot is similar to that of the Irish Nurses Organisation, which voted last month to accept the proposals by 54% to 46%.
