As per the Model Standing Orders precribed in the Industrial Employment 9Standing Orders) Central Rules 1946, the payment of Subsistence Allowance is to be regulated as follows:
(b) A workman who is placed under suspension under Cl. (a) shall, during the period of such suspension, be paid a subsistence allowance at the following rates, namely:
(i ) Where the enquiry contemplated or pending is departmental, the subsistence allowance shall, for the first ninety days from the date of suspension, be equal to one-half of the basic wages, dearness allowance and other compensatory allowances to which the workmen would have been entitled if he were on leave with wages. It the departmental enquiry gets prolonged and the workman continues to be under suspension for a period exceeding ninety days, the subsistence allowance shall for such period be equal to three-fourths of such basic wages dearness allowance and other compensatory allowances:
Provided that where such enquiry is prolonged beyond a period of ninety days for reasons directly attributable to the workman, the subsistence allowance shall, for the period exceeding ninety days, be reduced to one-fourth of such basic wages, dearness allowance and other compensatory allowances.
So the formula is 50% Basic+ DA+ Allowance for the first 90 days and thereafter it is either 75% or 25% as the case may be depending on whether such disciplanary enquiry is prolonged beyond a period of ninety days for reasons directly attributable to the workman.
