A salary increase justification is any circumstance or reason that employers accept to raise the salary of an employee. Salary increases can be justified by added responsibilities, prevailing industry rates and an employee's past performance.
Employers can be more easily persuaded to raise an employee's salary if the employee provides sufficient proof of the value that he has contributed to the company. Businesses usually raise the salary of valuable employees to dissuade them from moving to higher-paying positions in other companies. A staff member who has displayed consistent positive performance is also a more likely candidate for an increase in compensation.
