gender in the work place

For Writing Project 3, I'd like to explore the topic of discrimination and prejudice based on gender in the workplace.  Two terms I would focus on are "Glass Ceiling," "The limited advancement of a qualified individual (a woman) within the hierarchy of an organization because of discrimination"(Glenn 94) and "Mom Bomb," "The effect of motherhood on the pay of female managers" (Glenn 121).   The two lenses I would approach this subject from are the sociological and historical lenses.  I want to do research and then argue whether or not these terms (because they were terms coined over thirty years ago) and the discrimination of females in the workforce are still relevant in the 21st century.
