Section 226(2B) of the Trade Union and Labour Relations (Consolidation) Act 1992 (“the 1992 Act”) (inserted by the Trade Union Act 2016 (c.15)) introduces a new 40% threshold of support that must be satisfied in ballots for industrial action in important public services. This applies unless the union reasonably believes that a majority of those balloted are workers who are not normally engaged in the provision of important public services.
