It is correct that overtime payment, as per Section 14 of the Minimum Wages Act, is applicable only to those who are receiving minimum wages and not to employees who are receiving more than what the minimum wages notification states. Municipal Council Vs. Bhagat Singh (AIR 1998 SC 1201), State of Gujarat Vs. Savilal H Shah [2003 (11) LLJ 641 (Guj)], and many other verdicts support this.
However, Section 14(2) states that nothing in this Act shall prejudice the operation of Section 59 of the Factories Act in any case where those provisions are applicable. Similarly, the Mines Act, Plantations Labour Act, and the Shops and Commercial Establishments Act also have similar provisions for the payment of overtime wages to employees without any conditions regarding statutory minimum wages. The only condition is that supervisors and managers are not entitled to receive overtime wages. Unfortunately, this provision is not available in the Minimum Wages Act. Still, under the Minimum Wages Act, overtime payment can be claimed even by a manager whose salary is fixed according to minimum wages. It is also important to note that minimum wages are set not only for workers but also for supervisors, foremen, and managers.
Therefore, if the Factories Act mandates paying overtime at double the rate of normal pay, it should be paid regardless of whether the employee is receiving wages at the government-notified minimum wage level or not.
