Basic Salary Requirements Question:

Most often, the simple reason is that employers want an easy screening device to help sort applicants and those applicants with a salary requirement too low or too high are discarded. Other times, the employer is looking to save money by hiring a job-seeker at the low end of a salary range. In either case, it is not really fair to the job-seeker. With a salary history, employers also want to see frequency and size of raises and promotions.
