SIPTU members in Bord na Móna Recycling have voted to accept an offer from management, bringing an end to the threat of strike action.
Union representatives met with management in June, in a bid to resolve a dispute over the planned sale of the business.
SIPTU said the company offered significant improvements to the terms contained in a Workplace Relations Commission (WRC) proposal.
The offer was endorsed by the Bord na Móna Recycling Shop Stewards and recommended to members, who then backed the deal.
SIPTU said that while the agreement resolves immediate industrial relations issues, it remains concerned about the wider implications over the planned sale of the business.
SIPTU Divisional Organiser, Adrian Kane, said that many questions remain regarding the future direction of domestic waste services in Ireland.
The union said it has repeatedly called for a meeting with Minister for Climate, Environment and Energy Darragh O'Brien to discuss the issue but no date has yet been set.
In February, Bord na Móna said it had reached an agreement to sell its recycling business to KWD Recycling, subject to regulatory approval.
