Section 23 in Bihar Collection of Statistics (Work-stoppages resulting from Industrial and Labour Disputes) Rules, 1973
(23)"Loss in production" may be estimated from the average figures of three wage periods. This should be calculated by working out the value of normal approximate daily net output per manday and multiplying the same by the number of mandays lost on account of the work-stoppage. This should also be given separately for each of the calendar months during which the dispute was continued and their total as explained in 22 (ii) above.
