What is the glass ceiling? List the practices shared by corporations that shatter the glass ceiling.

Answers will vary. The glass ceiling is a transparent barrier that keeps women from rising above a certain level in organizations. In the United States, it has been rare to find women in positions above middle management. Although growth in opportunities for women to attain executive positions has recently stagnated, the situation is improving for women in the boardroom.
Corporations that shatter the glass ceiling share several practices:
i. Upper managers demonstrate support for the advancement of women.
ii. Leaders incorporate practices into their diversity management programs to ensure that women perceive the organization as attractive.
iii. Women are represented on standing committees addressing key strategic business issues and are targeted for participation in executive education programs.
iv. Systems are put in place to identify women with high potential for advancement. Please see the section "The Diverse Workforce" for more information.
