‘Under the Trade Union and Labour Relations (Consolidation) Act 1992 (“TULRCA”), s. 146, workers are protected against detriments falling short of dismissal related to taking part in the activities of an independent trade union at an appropriate time. The scope of “trade union activities” in that provision has been interpreted as not including industrial action.’
