If you want to increase what you are paid over the course of your career, don’t accept the first offer. Negotiate!
A big salary negotiation mistake is accepting the first counter offer. Many think they should jump at an employer’s initial counter offer, but it may actually be a trap that could cost you thousands of dollars over time.
If your immediate reaction to the company’s proposal is “I accept!” take some time to reevaluate the offer. Assess if there are other opportunities available for boosting compensation beyond what was offered.
Consider what you leave on the table if you accept the first offer. Then, negotiate compensation.
