Most people are uncomfortable negotiating offers, because they do not think it works, do not have a plan, or have not done their research to understand their true value. Because most employees do not negotiate when they first join an organization, workers are under-compensated by an estimated 10-25%. Salary increases are based on your initial salary, so it is well worth ensuring your first salary represents your true value to the organization. If you start off too low, it is very difficult to catch up later!
