What to do when your religion forbids you mixing with unrelated different gender human?

As it stands, Islam forbids unrelated men and women to mingle. But in a workplace, that's unavoidable. Here is a "clever" way out.

Sheik Abdel Mohsen Obeikan, a scholar and a consultant at Saudi Arabia's royal court, has called for women to give men breast milk to establish maternal relations and get around the ultra-conservative kingdom's ban on mixing between men and women who are unrelated.

"The man should take the milk, but not directly from the breast of the woman," UAE-based Gulf News quoted Obeikan as saying in local media reports. "He should drink it and then becomes a relative of the family, a fact that allows him to come in contact with the women without breaking Islam's rules about mixing."

Some Islamic scholars frown on the mixing of unmarried men and women. Islamic tradition, or hadith, stipulates that breastfeeding establishes a degree of maternal bond, even if a woman breast feeds a child who is not her own. [source]

But how can a women has milk without first having a baby? Does this mean that only women who have given birth to babies and have saved some breast milk can work in a mixed gender environment?
