You ask about the admonition that everyone must work, and want to know if this means that you, a wife and mother, must work for a livelihood as your husband does. We are requested to enclose for your perusal an excerpt, "The twelfth Glad-Tidings", from Bahá'u'lláh's "Tablet of Bi_sh_árát".(3) You will see that the directive is for the friends to be engaged in an occupation which will be of benefit to mankind. Homemaking is a highly honourable and responsible work of fundamental importance for mankind....
74: With regard to your question whether mothers should work outside the home,...
With regard to your question whether mothers should work outside the home, it is helpful to consider the matter from the perspective of the concept of a Bahá'í family. This concept is based on the principle that the man has primary responsibility for the financial support of the family, and the woman is the chief and primary educator of the children. This by no means implies that these functions are inflexibly fixed and cannot be changed and adjusted to suit particular family situations, nor does it mean that the place of the woman is confined to the home. Rather, while primary responsibility is assigned, it is anticipated that fathers would play a significant role in the education of the children and women could also be breadwinners.

In relation to your specific queries, the decision concerning the amount of time a mother may spend in working outside the home depends on circumstances existing within the home, which may vary from time to time. Family consultation will help to provide the answers....

The great importance attached to the mother's role derives from the fact that she is the first educator of the child. Her attitude, her prayers, even what she eats and her physical condition have a great influence on the child when it is still in the womb. When the child is born, it is she who has been endowed by God with the milk which is the first food designed for it, and it is intended that, if possible, she should be with the baby to train and nurture it in its earliest days and months. This does not mean that the father does not also love, pray for, and care for his baby, but as he has the primary responsibility of providing for the family, his time to be with his child is usually limited, while the mother is usually closely associated with the baby during this intensely formative time when it is growing and developing faster than it ever will again during the whole of its life. As the child grows older and more independent, the relative nature of its relationship with its mother and father modifies and the father can play a greater role.
