- From Wikipedia:
The Exit, Voice and Loyalty model states that members of an organization, whether a business, a nation or any other form of human grouping, have essentially two possible responses when they perceive that the organization is demonstrating a decrease in quality or benefit to the member: they can exit (withdraw from the relationship); or, they can voice (attempt to repair or improve the relationship through communication of the complaint, grievance or proposal for change). For example, the citizens of a country may respond to increasing political repression in two ways: emigrate or protest. Similarly, employees can choose to quit their unpleasant job, or express their concerns in an effort to improve the situation. Disgruntled customers can choose to shop elsewhere, or they ask for the manager.
Exit and voice themselves represent a union between economic and political action. Exit is associated with Adam Smith's invisible hand, in which buyers and sellers are free to move silently through the market, constantly forming and destroying relationships. Voice, on the other hand, is by nature political and at times confrontational.
While both exit and voice can be used to measure a decline in an organization, voice is by nature more informative in that it also provides reasons for the decline. Exit, taken alone, only provides the warning sign of decline. Exit and voice also interact in unique and sometimes unexpected ways; by providing greater opportunity for feedback and criticism, exit can be reduced; conversely, stifling of dissent leads to increased pressure for members of the organization to use the only other means available to express discontent, departure. The general principle, therefore, is that the greater the availability of exit, the less likely voice will be used. However, the interplay of loyalty can affect the cost-benefit analysis of whether to use exit or voice. Where there is loyalty to the organization (as evidenced by strong patriotism politically, or brand loyalty for consumers), exit may be reduced, especially where options to exit are not so appealing (small job market, political or financial hurdles to emigration or moving). Loyal members become especially devoted to the organization's success when their voice will be heard and when they can reform it.
