Restrictions on strike action The act declared unlawful
secondary action and any strike whose purpose was to coerce the government of the day directly or indirectly. These provisions were declaratory insofar as such strikes had already been ruled unlawful by Astbury, J in the ''
National Sailors' and Firemen's Union v Reed''. The act reaffirmed his judgment and gave it the force of statute law. In addition, incitement to participate in an unlawful strike was made a criminal offence, punishable by imprisonment for up to two years; and the attorney general was empowered to sequester the assets and funds of unions involved in such strikes.
Intimidation Section 3 of the act declared unlawful
mass picketing which gave rise to the intimidation of a worker.
Political levy Section 4 of the act mandated trade union members to
contract-in to any political levy which their union made on their behalf. This resulted in an 18% fall in the income of the
Labour Party, which was heavily reliant upon union funding.
Civil service unions Section 5 of the act enjoined civil service unions from affiliation to the
TUC and forbade them from having political objectives. ==Repeal==
