There are many reasons why, as a CEBS student, you should join your local chapter. The most obvious one is to receive a discount on the educational programs. Perhaps the most valuable benefit is the networking. Most people think networking is what you do when you are looking for a new job or have lost your job. That is not the most effective time to network.
Local chapters are perhaps the best avenue to pursue networking.
Better yet, volunteering for a committee lets people get to know you and your capabilities. People feel much more comfortable recommending or referring individuals after they have seen them at work. Don't overlook the fact that networking can help you in your current job. One Society member started a new job and one of her responsibilities involved an area of benefits she didn't know. Her boss wanted her to get answers to specific questions.
