The National Labor Relations Act (NLRA) was enacted in 1935 and has had two major amendments (along with many smaller ones).
The Wagner Act was selected by the National Archives as one of 100 Milestone Documents of American History.
The NLRA is codified at 29 U.S.C. §§ 151-169.
Note: lawyers and judges often refer to the original section numbers, rather than the U.S.C. section numbers—for example, saying "Section 1 rights" or "an 8(a)(1) violation."

These volumes give a sense of how much labor law has been developed by case law. For example, in U.S.C.A. an entire volume is devoted to 29 U.S.C.A. § 158 (§ 8 of the Act). The statute itself takes up 7 1/2 pages. Annotations take up the remainder of the 1112-page volume.
