it is because the displacement of load being horizontal,is normal to the direction of force of gravity ie.,cos 90' which is zero but he surely does some work if we consider it against the force of friction.
Work is said to be done where certain displacement is involved. Ex. Of work not done is Coolie carrying Load on his head..

The work done by the coolie is zero because the force he exerts is in the vertical direction (lifting the load against gravity) while the displacement is in the horizontal direction. Work is only done when the force and displacement are in the same direction.
Other researchers have shown that African and European women carrying 70% of their body weight in controlled studies used more oxygen while head-carrying, in contrast to carrying a load on their backs. It also may be hard to balance on your head.
