paraphrase The text explains that labor law is not extensively covered because it is subject to frequent changes. This instability is largely due to the structure of the National Labor Relations Board (NLRB), which is a quasi-judicial body responsible for adjudicating labor disputes. The NLRB is composed of five members appointed by the President, each serving five-year terms with one member's term expiring annually. This setup can lead to significant shifts in labor law interpretations depending on the political leanings of the current President. Additionally, the inherent complexity of labor law and its susceptibility to change with different presidential administrations are reasons for the limited presentation of these topics in the text. Despite this, the textbook remains valuable for both unionized and nonunionized employees as it covers major employment laws that apply universally and highlights key differences in how union and nonunion employees are treated
