Most employees don’t negotiate their own salary. Several think think their work ought to speak for itself.
Yet, in most cases, your manager isn’t aware of all the work you do. They only receive a weekly or monthly update of your work. Besides, they keep track of several things that crowd out your contributions in their minds. Therefore, there is always a gap between what you have really achieved, and what they think you have achieved. A good salary negotiation merely aims to bridge this gap.
The real reason most people don’t negotatiate their salary is because negotiation is difficult. It requires us to have difficult conversations and face the fear of failure. Most people evade this fear by not negotiating. At the same time, however, they expect their managers to fulfil their demands. Oftentimes, this demand isn’t fulfilled and they are left frustrated.
Ask, and you shall receive. To negotiate is to ask elegantly. To not negotiate is to expect to receive something without asking for it.
