Section 2(ii) in The Collection of Statistics (Work Stopages Resulting from Industrial and Labour Disputes) Rules, 1968
(ii)"Work-stoppage" means stoppage of normal activity in a unit as a result of which the persons employed in a unit are forced to remain away from their usual duties. These are of two kinds: (i) due to industrial disputes, sympathetic and political strikes/ lockouts which may be due to the initiative from the employers (lockouts) or the employees (strikes) and (ii) due to reasons other than industrial disputes, e.g. due to shortage of power; fuel or raw materials, breakdown of machinery, accumulation of stocks, civil commotion, fire or catastrophe or any other similar cause beyond the control of the owners and workers.
