The mayor serves as the city's chief executive, meaning he can appoint representatives to New York City's government agencies, including, but not limited to the transportation, health, education, finance, police, and fire departments. He must also create a budget plan which will determine the funding that will be allocated to each of the city's agencies, which is passed after months of negotiation with City Council. The mayor is also responsible for proposing and vetoing laws that will effect the city as a whole, which requires him to work with federal and state lawmakers, a dynamic that makes maintaining relationships with his political peers pivotal in the mayoral role.
