The Trade Union Act 2016, which makes a number of changes to the way in which industrial action is organised, came into force on 1 March 2017.
The Act amends the Trade Union and Labour Relations (Consolidation) Act 1992, including Section 226 on the requirement to hold a ballot before any trade union action.
Under the new regime, a majority vote in favour of industrial action will only be regarded as having the support of a ballot if at least 50 per cent of those entitled to vote did so. Different rules will apply, however, before industrial action in 'important public services' can go ahead. These include the health, fire, transport and border security sectors, plus public education provision to those aged under 17. In such disputes, a further test is to be applied whereby 40 per cent of all eligible union members must vote in favour of the industrial action for it to be legal.
