 This became known as the Valla affair and sparked enormous media interest in Valla, generating heated debate over her future as leader of the Norwegian Confederation of Trade Unions.On 9 March, under massive pressure, she announced her resignation after an inquiry appointed by the Executive Committee of the Norwegian Confederation of Trade Unions concluded that she had harassed Yssen and that she and LO had violated several Norwegian labor laws.Later in 2007 Valla published a book about the Valla affair, titled "Prosessen" (after Kafka's "The Trial").
