Most people act as if gender roles are fixed, so they expect females to do what they consider female work: cook the food, wash the clothes, clean the house, pick up the kids from school, and so on. They expect males to cut the grass, wash the car, go to work and bring home more money than the female. The truth is that any gender can do any of these tasks. Real-life experiences include women being barred from driving a sixteen wheeler and men being barred from being a secretary because they like to do jobs that are not considered fit for their gender. Real-life experiences include discrimination against women who work beside men and are paid less because the women are considered less able to work at a "man's job." Men and women in the workplace should be judged on their skills and potentials, not on gender.
Sexual roles are the only roles in which gender is limited: a man will never get pregnant, and a woman will never donate sperm. Other than reproductive roles, all others are open for grabs and gender should never be the deciding factor in who gets the job.
