Do you mean employment on being a lawyer or actually being a lawyer? If you want information about people who study the law, lawyers and the judicial system and its effect on society then you should look at sociology and professors of law at school. NYU offers a class called 'Law and Society' and it is about the study of law as a political practice.
If you want to know where you can work as a lawyer you will obviously work in a law firm for one, the police department for another and the armed forces are another.
