Our International has set forth many great objectives for its local unions to follow in our mission to secure our rights, advance our interests as workers, and build an organization where all the working members of our craft can participate. To build a forum that encourages the exchange of ideas on problems, which our welfare and prosperity depends. Establish order and harmony, and to encourage the principal and practice of negotiation and arbitration in the settlement of all differences between labor and management.
