The Unite trade union, which represents 6,000 workers in the public service, has decided to co-operate with implementation of the Croke Park Agreement, despite members voting to reject it.
The decision came at a meeting of Unite's public sector representatives this morning.
There had been a suggestion that Unite might withdraw from the Public Service Committee of Congress, given that the overall Congress vote had been in favour of Croke Park, while Unite's members had opposed it.
However, it was decided that Unite would enter the implementation process to protect its members from any victimisation that might occur.
Regional Secretary Jimmy Kelly warned that members would expect to see reimbursement of pay cuts commencing early next year.
The Association of Secondary Teachers in Ireland has decided to enter preliminary discussions with the Department of Education to get clarification for the proposals contained in the education section of the Croke Park Agreement.
The decision was taken at a meeting of the union's Standing Committee today.
Last week the Teachers' Union of Ireland executive decided not to endorse the overall Congress vote in favour of Croke Park because its members had rejected the agreement.
However, consideration of any potential industrial action has been deferred until later this summer.
The committee reiterated its rejection of the Croke Park agreement.
The Civil Public and Services Union, which also rejected the pay agreement, is re-balloting its members in September to see whether they want to abide by the overall Congress vote in favour of the deal.
