To be legally compliant, you have to follow a balanced outlook.
Overtime Rates and Legal Compliance
Please note that OT rates are double as: Under Sec. 59, it is mentioned that where a worker works in a factory for more than 9 hours in any day or for more than 48 hours in any week, he/she shall, in respect of overtime work, be entitled to receive wages at the rate of twice his/her ordinary rate of wages.
Thus, if you have 100 employees, you are paying approximately Rs. 1,27,800 per day, including overtime, based on a Central Minimum wage of Unskilled daily wage of Rs. 639.
Calculating Overtime Wages
The hourly daily wage is Rs. 80, and hence the OT rates will be Rs. 160. Therefore, the daily wage for Unskilled will be Rs. 1278 (for 4 hours OT in addition to 8 hours normal working day).
Implementing Shift Work
It would be ideal to introduce SHIFTS of 8 hours in your establishment with 50% of employees coming in 2-3 hours early from the next shift. In addition, if you feel that you need full strength for a given shift, you can recruit more employees for the shift in proportion and still pay the same daily wage for all employees to the extent that you will be paying overtime.
The greatest benefit will be more productivity and employment for many.
