The glass cliff is the phenomenon of women in leadership roles, such as executives in the corporate world and female political election candidates, being likelier than men to achieve leadership roles during periods of crisis or downturn, when the chance of failure is highest. The glass cliff is the phenomenon of women in leadership roles, such as executives in the corporate world and female political election candidates, being likelier than men to achieve leadership roles during periods of crisis or downturn, when the chance of failure is highest. The term was coined in 2004 by British professors Michelle K. Ryan and Alexander Haslam of University of Exeter, United Kingdom. In a study, Ryan and Haslam examined the performance of FTSE 100 companies before and after the appointment of new board members, and found that companies that appointed women to their boards were likelier than others to have experienced consistently bad performance in the preceding five months. This work eventually developed into the identification of a phenomenon known as the glass cliff— analogous to the concept of a glass ceiling, but implying the inability to perceive the dangers of the cliff's transparent edge rather than the false promise of elevated organizational positions which can be 'seen' through a ceiling of glass but which are actually unattainable. Since the term originated, its use has expanded beyond the corporate world to also encompass politics and other domains. Ryan and Haslam's research showed that once women break through the glass ceiling and take on positions of leadership they often have experiences that are different from those of their male counterparts. More specifically, women are more likely to occupy positions that are precarious and thus have a higher risk of failure—either because they are appointed to lead organizations (or organizational units) that are in crisis or because they are not given the resources and support needed for success. Extending the metaphor of the glass ceiling, Ryan and Haslam evoked the notion of the 'glass cliff' to refer to a danger which involves exposure to risk of falling but which is not readily apparent. CEO tenure is typically shorter at companies which are struggling, compared to those which are stable. The glass cliff concept has also been used to describe employment discrimination experienced by leaders who are members of minorities or disabled. Evidence of the glass cliff phenomenon has been documented in the field of law. A 2006 study found law students were much likelier to assign a high-risk case to a female lead counsel rather than a male one. A 2010 study found undergraduate students in British political science likelier to select a male politician to run for a safe seat in a by-election, and much likelier to select a female candidate when the seat was described as hard to get. Other research has failed to confirm the existence of glass cliff phenomenon. A 2007 study of corporate performance preceding CEO appointments showed that women executives are no more likely to be selected for precarious leadership positions than males.
