It all depends on what part of advertising/ marketing you want to work in. To work in the creative side (design of ads, slogans etc.) you don't neccesarily need a degree, so long as you can show your ability in an interview. The hours in this line of work do vary and from time to time you will need to work over-time.
Gender roles are socially acceptable and expected rules of behavior for men and women. When people think of gender roles, they often consider traditional roles that dominated the early and mid-20th century in the United States. In these roles, men were the breadwinners of the family, and the women took care of the house and children. These rules of behavior were taught from one generation to another.
Gender roles are the social and behavioral norms considered appropriate in social situations for people of different genders. An understanding of these roles is evident in children as young as age 4 and are extremely important for their social development. Gender roles are influenced by the media, family, environment, and society. A child's understanding of gender roles impacts how they socialize with their peers and form relationships.
