15-2. To understand how to deal with unions, one should understand labor law and unfair labor practices. The laws encouraging the union movement included the Norris–LaGuardia and National Labor Relations (Wagner) Acts of the 1930s. These outlawed certain unfair employer labor practices and made it easier for unions to organize. The Taft–Hartley or Labor Management Relations Act of 1947 addressed keeping unions from restraining or coercing employees, and listed certain unfair union labor practices.
In the 1950s, the Landrum–Griffin Act (the Labor Management Reporting and Disclosure Act) further protected union members from possible wrongdoing on the part of their unions.
