Explanation of Key Labor Case Issues
Description
Book Introduction
Human life and labor are inseparable.
Because life is work, and work is life.
In the past, labor was a burden that had to be endured in order to make a living.
It's different now.
It is a means for the realization of each individual's personality, and at the same time, it is a medium that prevents that individual from being cut off from society.
Labor law has become a law that protects us throughout our lives.
Unfortunately, laws cannot be perfect.
The same goes for labor laws.
Even the most skilled legislators cannot anticipate and establish regulations for every conflict that may arise in the workplace.
Legislative flaws are therefore inevitable.
Especially in the area of labor law, changes in the workplace are occurring at an almost unimaginable rate, but legal revisions are relatively slow.
When a gap arises between law and norms, it ultimately falls to the judges to fill that legislative gap.
Judges resolve conflicts in the workplace, keeping in mind the legislator's original intention.
This is precisely why an accurate and in-depth understanding of case law is considered important, especially in the field of labor law.
For those studying labor law to prepare for exams like the bar exam and the Certified Public Labor Attorney exam, memorizing case law is inevitable. However, we sincerely hope that this process will provide an opportunity to examine human life from the perspective of justice and equity amidst the dramatic changes in the labor market.
This is because labor law will soon be freed from the swamp of excessive ideology and established as a system of laws governing labor, which is our very life, from the perspective of fairness and justice.
This book selects the most important precedents in the field of labor law, both academically and practically, and provides commentary focused on the issues to facilitate an understanding of the institutional significance of these precedents.
Clearly, without Dr. Lee Jae-hyun's sincerity as a labor law scholar and his sensibility as a practitioner, even planning would have been a challenge.
I would like to take this opportunity to express my deepest gratitude.
I sincerely hope that all readers of this book, including test-takers, will go beyond the literal meaning of labor judgments and return to the basics, reconsidering the importance of "concepts" in labor law.
I sincerely support all of you who are struggling to achieve your dreams and goals today.
