Essentially, law is the way society regulates its behaviour. The intention of the legal industry is to create rules regarding conduct that are understood and respected throughout the population and to run an effective system for adjudicating disputes and crimes.
Civil law is generally related to disputes between individuals, while criminal law is concerned with crimes against the government (or crimes that break laws the government has set).
A typical way to enter the law industry is to become a paralegal, a support person who does everything from filing to legal research. Many paralegals end up going to law school.
Lawyers also play a big role in the industry. They actually spend most of their time researching and doing paperwork, although some lawyers argue cases before judges or juries. There are many different kinds of lawyers with different specialities.
Once someone has extensive experience and education in law they can go on to become a magistrate or judge and preside over and decide cases.
Working in the law industry often involves long hours in a stressful, deadline driven environment. Most people who work in the industry carry a lot of responsibility on their shoulders and often have to deal with people who have been accused of a crime or who are victims of crime, which can sometimes be difficult. In general, people who work in this industry do have the satisfaction of providing a key service to the community as they serve as advisors, advocates and protectors.
Responsibilities vary widely within the law industry. Most law professionals can expect to work in an office environment that can tend to be fast paced and stressful. Research is often a big part of the role. Barristers are required to research existing laws and past cases in order to provide legal advice and represent their clients in court proceedings or negotiations. Many law professionals write legal documents or work in an advisory capacity. Other roles that exist in the industry include Magistrate, Court Messenger, Law Clerk, Judge, Mediator, Court Reporter and Solicitor.
