The work done by the man is zero, technically.

Explanation:

Work done by the body is the product of the force applied to the body and the displacement done.

W  =  F d

According to the theory, if force is exerted, the body should be in motion. As the person stood still in the same place, displacement d=0

W = F*0 = 0 units.

Therefore, no work is done by the person according to the work-displacement theory.
