Lobby day
Lobby Day (also known as Advocacy Day) is a name used by non-governmental organizations (NGOs) for select days, often annual, when lay members meet politicians or public servants at various levels to advocate and explain support for legislation relevant to the NGO. While a national lobby day may be held by the national leadership of an organization, its regional or local affiliates may hold their own separate lobby days in order to not compete with the lobby.
