If
the action is made by workers using just their own force (and at most a hand
tool), then we call it manual work.
In
forestry, manual work is not so rare as we might think. Much tree planting is
based on manual work. Even in harvesting operations, the axe and the hand saw
have been popular for a long time, and they still are in those countries where
labor is cheap.
Strictly
speaking, the use of animals is not manual work proper, since workers do not
use their own force to perform the action. But we shall include it into the
manual work category for the sake of simplicity.
