According to psychologist Henri Tajfel, what are the basic strategies that people employ when positive social identity is threatened?

What will be an ideal response?

When positive social identity is threatened, people employ three basic strategies. If group boundaries are permeable, they may move between groups (social mobility). In the global marketing contexts, social mobility strategies may cause associates within the company, its agents, distributors, or other important stakeholders to resign or give their allegiance to a competitive firm that does not evoke a perceived threat to positive social identity. If social mobility is not possible, people may respond to identity threats with social creativity (i.e., attempt to improve the desirability of group membership by associating groups with positive characteristics) or social conflict (i.e., actively challenge group desirability or overturn existing or imposed order). Social creativity or social conflict strategies may threaten harmonious relations within the company, distribution channel partners, or customers.
