Provided the term employment is used in its wider sense as meaning work which is of economic
value not only to the family but to the community as well.
It might mean that women have at all times been thus employed. In primitive societies and in
agricultural communities women shared in the productive work on the land, in the workplaces and

labour is low, women's active participation in the daily work is indispensable. Today, women work in
the fields in all agricultural communities; they spin and weave, do building work and various other
kinds of hard physical labour in many parts of the world which have not yet achieved the objectives
of industrialisation.
