PFIZER (P) LTD. BOMBAY vs THE WORKMEN

The Supreme Court held that the introduction of three shifts in the appellant's factory was necessary for the continuous production of the drug P.A.S., which required 20 hours of manufacturing time. The Court found that the Tribunal's concerns regarding inconvenience to employees and the quality of production were unfounded, as the introduction of three shifts would enhance both quality and quantity of output. The Court allowed the appellant to implement the three shifts while rejecting the employees' appeal against the reduction of paid holidays from 27 to 10, affirming the Tribunal's decision on that matter under the Industrial Disputes Act, 1947, sections 10(1)(d) and 12(5).
