A glass ceiling is a term used to describe the unseen, yet unbreakable, barrier that keeps one from rising to the upper rungs of the corporate ladder, regardless of qualifications or achievements.”
Initially, and sometimes still today, the metaphor was applied by feminists in reference to barriers in the careers of high achieving women. In the US the concept is sometimes extended to refer to obstacles hindering the advancement of minority men, as well as women.
David Cotter and colleagues defined four distinctive characteristics that must be met to conclude that a glass ceiling exists. A glass ceiling inequality represents:
- “A gender or racial difference that is not explained by other job-relevant characteristics of the employee.”
- “A gender or racial difference that is greater at higher levels of an outcome than at lower levels of an outcome.”
- “A gender or racial inequality in the chances of advancement into higher levels, not merely the proportions of each gender or race currently at those higher levels.”
- “A gender or racial inequality that increases over the course of a career.”
Cotter and his colleagues found that glass ceilings are correlated strongly with gender. Both white and African-American women face a glass ceiling in the course of their careers. 
The glass ceiling metaphor has often been used to describe invisible barriers (“glass”) through which women can see elite positions but cannot reach them (“ceiling”). These barriers prevent large numbers of women and ethnic minorities from obtaining and securing the most powerful, prestigious, and highest-grossing jobs in the workforce. Moreover, this effect may make women feel they are not worthy to fill high-ranking positions or as if their bosses do not take them seriously or see them as potential candidates for advancement.
