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.
Breaking down the gender role barriers. Men are the breadwinners. Women belong in the kitchen. Men go to work. Women watch the children. Men are the heads of households. Women are the housekeepers. These are age-old stereotypes that belong in the 1950s, yet they still exist in society today. Gender roles are common and well-integrated into American society, though they have become less-stressed over time.
