Unit 5.2 DB: Unequal Treatment in Professions

Many professions today still have gender stereotypes associated with them. In the past decade or so, many have begun to "open their doors" to other genders such as the military, nursing, sports media/broadcasting, law enforcement to name a few. Why has it taken so long for these gender barriers to come down? Why did they exist in the first place? Students can also talk about the struggles we see even when the professions are opened up to other genders. Use examples and even a case study to support your thoughts. 

You must support your response with scholarly sources in APA format.
