The Master and Servant Act 1867 (30 & 31 Vict. c. 141) was an act of the Parliament of the United Kingdom which sought to criminalize breach of contract by workers against their employers.
Although it did still give employers and prosecutors warrant to prosecute breach of contract the act was more progressive than the former standard set by the Combinations of Workmen Act 1825 (6 Geo. 4. c. 129) whereby employees seeking to form labor unions and such could be prosecuted for criminal conspiracy in restraint of trade. Under the new standard employees could only be charged for "aggravated cases" and breach of contract, which was at the time seen as an improvement.
Of note is the fact that this piece of legislation was passed by the conservative statesman Benjamin Disraeli and his likewise conservative political bloc.
Section 1 of the act provided that the act may be cited as The Master and Servant Act, 1867.
Section 25 of the act provided that nothing in the act would extend to or be made applicable to any enactment in the first schedule to the act in relation to Ireland or any part of Great Britain.
The Employers and Workmen Act 1875 (38 & 39 Vict. c. 90) was passed in substitution for the act.
The whole act, and all non-excepted enactments listed in the first schedule to the act, were repealed by section 17 of the Conspiracy and Protection of Property Act 1875 (38 & 39 Vict. c. 86).
