Women "becoming" men in the workplace

I remember reading the linked article from another sociology class! I do believe that women entering into workplace as "conceptual men" is not only problematic but highly inefficient for both the workers and the employers. Considering that many women go through pregnancy and childbirth at one point in their lives, the status as conceptual man is extremely temporary and easily taken away. The fact that various corporations and institutions are setting the default worker as males and give female workers the ultimatum to choose between continuing on with the conceptual man status by sacrificing family life or giving up their professional career in order to become a mother reflects how unequal our society is towards women.
