Leaving aside any written contract (including any union or collective bargaining agreement) you may have, there is NO right to an annual wage review. In the absence of a contract to the contrary, the employer determines how much to pay you, if and when to give you a raise (they don't have to ever give you a raise; all raises are voluntary when there is no contract), how much of a raise to give if they chose to provide one, etc. Without a contract, all aspects of your pay are 100% at the empoyer's discretion or choice.If you do have a written contract, you have whatever rights (e.g. to reviews; to raises) that the contract itself gives you by its plain terms.
