What are the company's policies regarding the frequency and timing of employee reviews? Start by checking your employee handbook and make sure you completely understand the policies. You then have a decision to make: you can approach your boss to discuss the matter and try to work it out, you can talk to your HR professionals to ask them to address it on your behalf, or you can wait and ask if any adjustment to your compensation can be made retroactively, in light of the delay. Each strategy carries risks. The first two risk impacting your long term relationship with your boss. The last strategy is a financial risk but preserves the relationship. You have to ultimately decide what's most important to you, and what consequences you're willing to live with. Happy to talk with you directly if I can be of more help.
