Friend the work done is zero in three conditions :

1) When there is no displacement

2) When the displacement is normal to the direction of force. Ex- A collie carrying a Load in his head.

W=s.F.cosx . when a person tends to change the position of the object but there is no displacement by the applied force then the work done by the applied force on the object is 0 .
