The conflict that can arise when rules on competition law and the right to bargain collectively intersect has been a live issue amongst those interested in employment relations in Ireland for more than two decades now, as a series of conflicts has arisen in this space.

It will focus, particularly, on some paradigmatic disputes and reflects on how Irish law generally views the restriction on ‘economic freedom’ inherent in collective representation rights.
