The Constitution Alteration (Industrial Employment) Bill 1946,[1] was an unsuccessful proposal to alter the Australian Constitution to give the Commonwealth power to make laws regulating employment in industry.

It was put to voters for approval in a referendum held on 28 September 1946.

The proposals was narrowly rejected, with a minority of 1.80% in the fourth state, South Australia.

The proposal was to insert into section 51 that the Parliament have power to make laws with respect to::(xxxiv.A.)

Terms and conditions of employment in industry, but not so as to authorize any form of industrial conscription;[1]This was the sixth occasion in which the commonwealth sought power to regulate terms and conditions of employment, rather than using the conciliation and arbitration power, having been unsuccessful in 1911, 1913, 1919, 1926 and 1944.
