I don’t think you can checkmate your employer and attempting to do that will show them the risk and they’ll start working to mitigate it. You might get a raise in the short term and then be let go in a year.

For the CV question, ask yourself why would a company hire you over another applicant? Make sure you highlight that in the CV and that you apply to jobs where that is your competitive advantage. If you’re trying to change careers somewhat, you might have to make a “lateral move” for the same pay so that you can build skills.
