Practicing employment law can be very complex yet very fulfilling. It can involve employment discrimination suits, which range from race, sex, age or disability discrimation to cases which pertain to misappropriation of trade secrets or suits to enforce Non-Competition Agreements. You might represent the employee who feels wronged, or you could represent employers against those claims. If you defend the employers part of your responsibility would be to advise the employers how to best avoid these suits.
These cases typically involve complicated relationships between people in the workplace and therefore may be fraught with emotion and hurt feelings. There is a very human component to this field, so a prerequisite needed to practice in this field would be people skills. You must develop a real trust relationship with your clients and serve as their competent advisor, regardless of the side you argue. You should also possess excellent writing skills and ensure that you are up to date on the latest developments in the field.
Most people go to law school because they want to help people, argue in court, or work on sophisticated legal issues. Most do not belief a family law practice offers that, but they are mistaken. Helping individuals resolve problems, in contrast to making corporations more money, can be very fulfilling and will show you directly how your legal knowledge and skills can make a difference in someone’s life. Family law is also a very litigation based practice. Depending on the jurisdiction you practice in, there should be numerous opportunities to make court appearances, argue motions, or try the whole case, in the event negotiations are not successful. While many family law cases do not involve sophisticated legal issues, some do, and in those cases, you will be called upon to understand and argue complex business as well as family law issues. Because you will be dealing directly with people, you will also need a working knowledge of real estate, bankruptcy, will and estates and perhaps even criminal law. 
Tax law deal with the rules, policies and laws that oversee the tax process and can involve charges on estates, property, transactions, income, licenses and more by the government.

There are also many entities that are entitled to collect taxes, from the Federal level to the city or township level. The Federal tax practice has its own court and is a very detailed practice.
