In recent years a surge of conflicting laws and regulations have emanated from Congress, federal agencies, and the courts concerning the right of individuals and organizations to obtain what heretofore had been considered private information and the right of individuals and organizations to maintain the privacy of such information. To answer the host of questions involved in unions' rights to company information, the author was commissioned to make this study. Part 1 discusses the nature of disclosure. Part 2 discusses disclosure pursuant to the National Labor Relations (Taft-Hartley) Act, which requires employers and employee organizations to exchange all information relevant and useful in the collective bargaining process. Part 3 concerns the Federal Privacy Act of 1974 and employer-employee relationship. The relationship of the Freedom of Information Act and information policy is discussed in part 4. This act is a charter of rights under which members of the public can obtain access to governmental information. Part 5 discusses work-place chemical exposure and identity information, and affirmative action in employment data, both in regard to the National Labor Relations Board's (NLRB) scope of authority.
