Many organisations have formal appraisal systems which seek to determine how well someone is performing. These are notoriously subjective and it is just as critical knowing how the system works and getting on well with your boss or supervisor as it is performing well.
It is important though to make sure your achievements and contributions are noted and not glossed over or forgotten. One way to do this is to keep a diary and note your achievements or positive contributions for reference in your salary review.
You should also regularly seek comments on your performance from your supervisor/manager. This ensures that if there are any concerns these will be highlighted to you in time for you to remedy. Secondly by seeking feedback you will usually receive positive comments which means that for your review you will have already established a positive environment.
The following guide includes valuable hints and information about how to manage your performance appraisal and find opportunities to negotiate better outcomes at work.
