Referees

• As a final year student, you were probably advised to list two referees, one work related, one academic related.  If you've been working for a year or more, your lecturers might not remember you as clearly and a potential employer is probably more interested in hearing from someone who knows you in a work environment
  
• If you don't want your current employer to know that you're job-hunting, it's best to say "References available upon request" on your CV instead of giving names. That way  you control who is contacted for a reference and when.  In most cases it's better not to tell anyone in your current job that you're looking elsewhere.  If you tell your supervisor that you're jobhunting, and it takes several months to find something, you might get cut out of important projects or assignments.  If you're not going to tell your supervisor then don't tell anyone - word gets around!
  
• When the time comes to give a potential employer the names of your referees, be sure to ask the referees first 
• Your referees will find it helpful if you let them know who will be contacting them and if you tell them about the job you're going for and the things that you'd like them to emphasise.  You could also give your referees a copy of your CV to remind them of your background and experience.
