Quite simple this one!
Don’t. Unless you are in education or in academia where it is considered usual.
The vast majority of employers will request references at the time a job offer is made.
The only things you do when putting references on a CV is to take up space and to run the risk of someone (that you don’t know) making contact with your current employer and causing you a massive problem.
Don’t even put that “References are Available on Request” – people know that this is the case and, again, all you are doing is using up valuable space.
The only exception to this rule is education and the academic world where it is considered usual to put down referees on a CV as it can add weight to a job application.
