Even prior to the provisions in the Industrial Disputes Act, 1947 there was a provision for strike and lock-out in Section 15 of the repealed Trade Disputes Act, 1929. The Industrial Disputes Act does not purport to take away these rights of strike and lock-out from the labour and employer. However, for the purpose of achieving harmonious relations between the industrial employers and their employees, the rights of strike and lock-out have been restricted. The act has prohibited to resort to strike and lock-outs continued or commenced in contravention of these statutory provision have been made illegal by Section 24 of the Act.
The strike/lock-out situations can be divided into three parts:-
(i) pre-strike/lock-out situation
(ii) In-strike/lock-out situation
(iii) Post-strike/lock-out situation
