[2] Section 2 of the Act introduced a new requirement of 50% of union members to vote in a ballot for strike action.

[3] Section 3 requires that workers in important services (health, school education, fire, transport, nuclear decommissioning and border security) must gain at least 40% support of those entitled to vote in a workplace for a strike to be legal.

This was demanded by the House of Lords, during its passage through Parliament, since the existing law mandated the process of postal voting.

[3] Sections 5 to 7 requires more information about numbers of people voting and about results to be given to union members and to the Certification Officer.

Take for example the PCS Union pay ballot held in July 2018,[4] which produced the following result: Under previous legislation, this would have been sufficient for the union to call a strike, but there would have needed to be approximately 12,000 additional votes cast in this ballot to reach the 50% turnout threshold.
