UNI Global Union is a clearing house for information, particularly regarding international productions or movement of employees across national borders. It is concerned with issues ranging from ownership, trade policy and technological change to copyright, piracy and censorship. It acts to exchange information about collective agreements, legal standards and practices, aiming to temper labour relations and practices with common minimums in consultation with employers and employees.
