The laws apply only to the organised sector. Chapter V talks about the most important and often in news topic of 'Strikes and Lockouts'. It talks about the Regulation of strikes and lockouts and the proper procedure which is to be followed to make it a Legal instrument of 'Economic Coercion' either by the Employer or by the Workmen. Chapter V-B, introduced by an amendment in 1976, requires firms employing 300 or more workers to obtain government permission for layoffs, retrenchments and closures. A further amendment in 1982 (which took effect in 1984) expanded its ambit by reducing the threshold to 100 workers.
