Ah. That's a good question. I found the original text allowing unions in government. To quote: "WHEREAS participation of employees in the formulation and implementation of personnel policies affecting them contributes to effective conduct of public business; and
WHEREAS the efficient administration of the Government and the well-being of employees require that orderly and constructive relationships be maintained between employee organizations and management officials; and
WHEREAS subject to law and the paramount requirements of the public service, employee-management relations within the Federal service should be improved by providing employees an opportunity for greater participation in the formulation and implementation of policies and procedures affecting the conditions of their employment; and
WHEREAS effective employee-management cooperation in the public service requires a clear statement of the respective rights and obligations of employee organizations and agency management:" (http://www.presidency.ucsb.edu/ws/index.php?pid=58926)
