Dear Shamal,
Overtime (O.T.) specified under the Factory Act requires paying double the rate of normal pay. This means that what you are paying an employee for 1 hour normally, he must be paid for 2 hours when doing overtime.
For instance, if the overtime hours are 10 and the salary is 3000/-:
3000/26/8 = 1 hour salary, i.e., 14.42 * 2 = 28.84 * 10 = 288.46.
Therefore, you have to pay him Rs. 288/- for his 10 hours of overtime. Please note that this calculation is based on the presumption that your factory is under the Factory Act. The rules may differ if covered under the Shops and Commercial Establishments Act.

KIRAN KALE.
