When the Time is Right
The most commonly agreed upon date to ask for a raise is at the end of each fiscal year if it is not explicitly tied to your yearly evaluation. There are some factors that can play into your timing, of course, like company-wide layoffs, new hires, and etc. This should be considered, but it shouldn’t instantly void your case for a raise.
negative impact on your chances for a raise is if you didn’t bother to ask any of your colleagues or check employee handbooks to ensure that there is nothing specifying raises. Sometimes the end of the year is too late to ask and budgets are already finalized.
What’s the Best Approach?
No matter how you get there, be prepared with your questioning and be prepared to talk about yourself like you’re the star player on a team going for the franchise tag. Tell your boss that you have notably improved your skills and that you feel your value as a member of the team has gone up. Let them know that you are now taking command of more responsibilities, your number of mistakes is much lower, and you would like a salary that serves as motivation to keep pushing for excellence.
