doing the dirty work

While I was  reading "Doing the dirty work" I realized that even now in the 21st century jobs are still being categorized by gender. When we think of a housekeeper we automatically think of a women and when we think about a janitor we automatically think of a men. Even if men are doing cleaning jobs now the place where they work and the name they give the job makes a big difference. Most people think that a janitor's job it's hard and you need to be strong for it therefore we need men to do those types of jobs because they are strong.and  of course this is not necessarily true because housekeeping is as hard as being a janitor is but just because it's home related people associate house keeping with women..
