Is it appropriate to ask for a raise during a review?

if this is for a different job than you have now you need to know at the outset what the rate is going to be

if it isn't at least more than you are currently getting you won't be any better off but have a different responsibility

and no, asking for a raise in a job you haven't even performed yet is not wise

I wouldn't bring up how much work the three of you are covering until he finds someone.

Just say, "I've been here for over a year, I've proven myself to be a hard worker who can produce results for you, and I'd like to negotiate a raise to reflect that."

They should be offereing you a raise with your review assuming its a good review. 1 1/2 yrs. is planty of time for them to have offered you a raise. You should ask.

No, don't ask DURING the review. The purpose of the review is to discuss your performance, not your compensation. It's rude and unprofessional to hijack the purpose of the meeting.

If the review goes well, you are free to approach your employer about renegotiating your compensation at another time.

Normally you get a raise if you have good performance reviews (after a year of being with the company) so check out your next pay check after that and see if you got one.

If you don't get one then have a chat with your boss about getting a raise.

If there's a job you're interested in then apply for it and let your boss know what job you're interested in.

Yes, if you can justify a raise then the appraisal is the proper time to ask. Two ways you do not justify a raise - 1) I haven't had one in a year a half; 2) I am doing someone else's job temporarily. Go in to the appraisal prepared - have a list of your accomplishments (situations where you have gone above and beyond, not just done your job, n if you do it well).
