Pros
Yellow book offers good pay if you can keep up with your sales quotas and make all of you sales goals. there is generally a lot of freedom with your time because you make your own schedule and set up your own appointments to meet customers. there are also good benefits for employees.
Cons
HIGH PRESSURE! As a sales representative you are expected to hit very difficult sales goals and quotas. If you do not hit your goals you will not make your bonus (which is where your real pay comes from). If you do not hit your goals you will be under constant threat of loosing your job. territories in which you solicit customers are assigned by management so if you are not favored by specific managers you may get stuck trying to sell products in parts of town in which there is not much business.
