I can sense you are facing 2 problems. The first is your employer is forcing you to resign because your salary is at the high side. The second problem is you are not getting any opportunity from other places to get another job. Let me help to address these 2 problems with some recommendation. No one has the right to force you to resign just because your salary is at the high side. Your employer should either expand your role or deploy you to another department in the company which needs your expertise. If they are not doing that, then they can offer you a retrenchement package to make you leave. However it is up to you to accept or reject it. You have the right to reject it if the package is unattractive or you still want to work in the same company. My recommendation is, book an appointment with your boss to discuss your future. Please remember not to be emotional and talk based on facts. I’m sure if your boss is a reasonable person, you will be able to decide better on the options available for you after the meeting. If that does not work, then you either can tender your resignation with an attractive retrenchment package or look for other opportunity in other departments in the same company if that is available. Even it is hard to do so but you will need to move on with your
career.

For your second problem, if you don’t mind, please send me your resume or your application letter via e-mail : career_advisor@resumeweassist.com. From there I will be able to provide a better assistance.
Good luck!
