When you're asking your boss for a raise, you've got to establish the importance of this. The setting is important. You don't want to sort of chase after your boss on his or her way to an elevator Friday afternoon on the way to a holiday weekend. Oh my boss I need to rate that's not the time. It's too easy for them to why my recommendation is send an email or a call or a face to face encounter where you specifically asked for an appointment and say, Mr. Smithers, TJ, I need to schedule an appointment with you to talk about something important. If they ask what to say I'd like to talk to you about my future here at the organization.
You don't want to sound like you're upset. You don't want to sound like there's a panic. But you do want your boss to know this is important. You want his or her undivided attention. This is not something that you just To casually mentioned in the lunchroom one day, it's not something you mentioned is you're both leaving a meeting and scurrying to the next thing. So you've got to make sure you have your boss's attention.
In order to do that you need an appointment. And if your boss says two weeks from Tuesday find, I'd rather have it on the calendar and something specific. Then just leave things haphazard, or talk to someone down the hallway. So that's the first step. Make an appointment for this meeting to ask for a raise.
