There are several valid reasons to request a salary increase. These include expanding your industry expertise, assuming extra duties, and completing a significant project that benefited the company. Additionally, if your employer has had strong financial quarters, you‘ve received a better job offer elsewhere, or you‘re being paid less than the industry standard in your region, these are all valid reasons to ask for a raise. Finally, hitting your one-year mark at the company and receiving a positive performance review are also strong justifications for requesting a salary increase.
