Progressives focused on reforming three main areas: helping the urban poor through sanitary housing and reasonable living conditions, improving unsafe and unfair working conditions for workers, and reforming corrupt government practices at all levels of government. They achieved some successes like the passage of New York's Tenement Act of 1901 which required landlords to provide basic sanitation and the Triangle Shirtwaist Factory fire of 1911 which inspired new workplace safety laws. However, progressives still faced opposition to reforms from big business who opposed things like limits on the length of the workday.
