There were no special labor laws until about 1930, so employers were virtually
unrestrained in their behavior toward unions and employees. Since the Great
Depression, in response to changing public attitudes, values, and economic
conditions, labor law has gone through three clear changes: from strong
encouragement of unions, to modified encouragement coupled with regulation, and
finally, to detailed regulation of internal union affairs.
A. Period of Strong Encouragement: The Norris-LaGuardia Act (1932) and the
National Labor Relations or Wagner Act (1935) — The Norris-LaGuardia Act
guaranteed to each employee the right to bargain collectively free from
interference, restraint, or coercion; but it did little to restrain employers from
fighting labor organizations. The National Labor Relations (Wagner) Act of 1935
(1) banned certain unfair labor practices; (2) provided for secret-ballot elections

two provisions.
1. Unfair Employer Labor Practices — As deemed by the Wagner Act: (a) it is
unfair for employers to interfere with, restrain, or coerce employees in
exercising their legally sanctioned right of self-organization; (b) it is unfair for

passage of the Wagner Act in 1935, but the tide had begun to turn by the
mid-1940s.
B. Period of Modified Encouragement Coupled with Regulation — The Taft-Hartley
Act (1947) amended the Wagner Act with provisions aimed at limiting unions in
four ways: (1) by prohibiting unfair union labor practices, (2) by enumerating the
1. Unfair Union Labor Practices — (a) unions cannot restrain or coerce
employees from exercising their guaranteed bargaining rights; (b) unions
2. Rights of Employees — The Taft-Hartley Act protects employees from their
unions.
3. Rights of Employers — The Taft-Hartley Act explicitly gives employers full
freedom to express their views concerning union organization. The only
major restraint is that employers must avoid threats, promises, coercion, and
