Arthur works for the Ministry of Magic, initially in the Misuse of Muggle Artifacts office. He is obsessed with learning about Muggle customs and inventions and owns a large collection of mostly Muggle used items. His department, a minor and derided subsection of the Department of Magical Law Enforcement, lacked funding and his salary was insufficient to provide for a family of nine - leaving his family finances precarious. However, in Harry Potter and the Half-Blood Prince, he has been promoted to Head of the Office for the Detection and Confiscation of Counterfeit Defensive Spells and Protective Objects. His promotion was accompanied by a pay increase. Mr Weasley first officially appears in Harry Potter and the Chamber of Secrets, when Harry stays with the Weasley family during the summer before Hogwarts opens. In Harry Potter and the Goblet of Fire, it seems that Arthur does not fully believe the stories of Harry's abuse at the hands of the Dursleys until he witnesses what they think about Harry and the Wizarding world, before taking him to the Quidditch World Cup. After that, he takes a more active interest in Harry's welfare.In Harry Potter and the Order of the Phoenix, Mr Weasley is a member of the Order of the Phoenix and during one of his shifts in the Ministry of Magic the snake Nagini, which was acting under Voldemort’s control, attacks him. Harry, who is mentally connected with Voldemort, manages to see this in a vision and is able to warn the Hogwarts authorities. Arthur is subsequently saved just in time and sent to St Mungo's Hospital for Magical Maladies and Injuries. He was originally intended to die in that scene, but Rowling could not bear to kill him. He was also slated for death in the original draft for Harry Potter and the DeaThly Hallows. Rowling has said that part of the reason she could not kill Arthur as originally planned was that he is one of the only good fathers in the series. However, as she "wanted to kill parents," she spared Arthur's life in exchange for Remus Lupin's and Nymphadora Tonks's.
