Industrial Disputes Act, 1947 · Chapter IIA: Notice of Change

Section 9A: Notice of change

The Industrial Disputes Act, 1947 was repealed and replaced by the Industrial Relations Code, 2020 from 21 November 2025. It still applies to matters and proceedings from before that date, as the repealing law provides.

In plain words

An employer who wants to change any condition of service listed in the Fourth Schedule, such as wages, hours, leave or shifts, must first give the affected workmen notice, and cannot make the change within twenty-one days of the notice.

  • No notice is needed if the change follows a settlement or award.
  • No notice is needed for workers covered by government service rules such as the Fundamental Rules or Civil Services rules.
