The Trade Disputes Act of 1929 provided for

(a) the participation of workers in the management of industries.
(b) arbitrary powers to the management to quell industrial disputes.
(c) an intervention by the British Court in the event of a trade dispute.
(d) a system of tribunals and a ban on strikes. ✓ UPSC's answer

Why the answer is (d)

• The Trade Disputes Act, 1929 was passed amid rising labour militancy (Bombay textile strikes, 1928) and the Meerut Conspiracy Case.

• It provided for courts of inquiry and boards of conciliation (tribunals) to settle disputes, and made strikes in public utility services illegal without notice and banned general or sympathetic strikes intended to coerce the Government — option (d).

• It did not give workers a role in management (a), give management arbitrary powers (b) or involve British courts (c).

• Hence option (d).

Why the other options are wrong

(a) the participation of workers in the management of industries.: Workers' participation in management was not provided.
(b) arbitrary powers to the management to quell industrial disputes.: The Act set up tribunals, not arbitrary management powers.
(c) an intervention by the British Court in the event of a trade dispute.: It did not involve British courts.
