My employer classified my position on the job description that is not related to my everyday job in order to stop me from salary increase. But I also have another job descriptions that depicts my everyday job. Now I have two different job descriptions. Should I have the right to depend my position and ask for re-classification and salary increase?

Unless specifically negotiated for, non-unionized employees are generally not automatically entitled to salary increases. If you are unionized, please speak with your union rep about the misclassification.

The misclassification to prevent a salary increase for you cannot be based on discriminatory grounds, such as gender and race. If you believe this is a case of discrimination, you should consult with an employment lawyer immediately.
