A Grievance Mechanism (GM) is a system that allows citizens to provide feedback to implementers of a given service and allows implementers to respond. There are several important benefits to setting up strong GMs for social protection programmes, such as: increasing overall programme accountability and citizens' trust and involvement; continuously solving operational issues (complementary to monitoring and evaluation) and reducing the cost of addressing them; holding implementing authorities accountable at all levels of implementation to curb corruption; and standardising programme implementation and performance.
