However, two factors make Ireland distinctive within this classification of countries, firstly the system of national social partnership that prevailed from 1987 to 2008, and secondly, the absence of a statutory route to union recognition. In this paper, we examine the extent to which a new piece of legislation, the Industrial Relations Amendment Act 2015, provides unions with a route to securing bargaining rights for workers and extends collective bargaining rights generally. We conclude that the Act represents a missed opportunity to offer mechanisms to secure rights for unions and their members capable of delivering collective bargaining to the non-union sector. We situate the paper within debates concerning the role of labour law in supporting workers rights to collective bargaining.
