in physics
when Kohli carrying some load on his head moves on horizontal platform, in order to balance the load on a supply is a force on the load and the upward direction which is equal to its weight. His displacement is along the horizontal direction find the angle between weight on the Kohli and the displacement is 90 degree. Therefore the work done by him is zero
hence for your question we can say that
although of Coolie get exhausted by carrying his loads on his head work done by him according to physics is zero because the angle between weight on the Coolie and the displacement is 90 degree and cos theta 90 degree = 0 hence work done by Coolie according to physics is zero
