Dear Pavani
Any worker or Union may not go to the strike or stop the production with out giving notice to the employer earlier. This has been clearly explained in the Industrial Dispute act in the Chapter V Sec 22.
22. Prohibition of strikes and lock-outs -
(1) No person employed in a public utility service shall go on strike, in breach of contract
(a) without giving to the employer notice of strike, as hereinafter provided, within six weeks before striking; or
(b) within fourteen days of giving such notice ; or
(c) before the expiry of the date of strike specified in any such notice as
aforesaid; or
(d) during the pendency of any conciliation proceedings before a conciliation officer and seven days after the conclusion of such proceedings.
(2) No employer carrying on any public utility service shall lock-out any of his workman
(a) without giving them notice of lock-out as hereinafter provided, within six weeks before locking-out; or
(b) within fourteen days of giving such notice; or
(c) before the expiry of the date of lock-out specified in any such notice as aforesaid; or
(d) during the pendency of any conciliation proceedings before a conciliation officer and seven days after the conclusion of such proceedings.
