Casework refers to the process by which legislators, or their staff, assist individual constituents with issues or problems they are facing. This can include helping navigate government bureaucracies, advocating on their behalf, or connecting them with resources and services. Casework is an important function of legislatures, as it allows lawmakers to directly address the concerns and needs of the people they represent. It is a key way that legislators can demonstrate their responsiveness and commitment to serving their constituents.
