BURMAH SHELL OIL STORAGE & DISTRIBUTION COOF INDIA vs BURMAH SHELL MANAGEMENT STAFF ASSOCIATION& ORS.

The Supreme Court analyzed the definition of 'workman' under Section 2(s) of the Industrial Disputes Act, 1947, determining that the main work performed by an employee is crucial in classifying them as a workman. The Court held that members of six categories, including Transport Engineers and District Engineers, were not workmen, while it found error in the Tribunal's classification of Blending Supervisors. The ruling emphasized that incidental technical work does not qualify an employee as a workman if their primary role is supervisory.
