I keep a master list of references in a computer file and pick and choose based on which job I'm applying for today. Is it another SM gig? I list directors, artistic directors, peer SMs, and maybe senior designers/stagehands/wardrobe if they're notable, well-spoken, and know me well. Is it an office job? I list other theatrical staff, Trustees, former bosses in general, and anyone else who will speak about my professional skills. You should also have a cross-section of supervisors and peers in your references. This helps the company see that you do excellent work for your bosses but also that you're pleasant to work alongside.
Then, before I send the references to the hiring company, I contact my references to give them a heads-up. This is a wonderful chance for you to tell your reference why you think you'd be perfect for this job. This gives them an understanding of your goals and helps them say just the right things when the interviewer calls. If you get a particularly great job, write your references a short note thanking them for their help and support. This goes a long way!
I also do something a little different with my references - they're on a separate sheet of paper and formatted like this:
Joe Smith
Artistic Director
Company
Phone: XXX-XXX-XXXX (office)
Email:
joesmith@h0tmail.comMr. Smith is a favorite local director and promoter in the City arts scene. He has led Company Name for over 12 years. Mr. Smith worked with Lauren when she stage managed the successful 25th Anniversary season (2004-2005) with Company Name.
This is unusual - but it works very well for me. But it lets the interviewer know something about your reference so that they have some awareness when they call. I include my sheet of references with my resume if I know references will be needed. If they ask for references later, I can email or mail this sheet. I can't stand wasting space on my resume with the references. And I don't like seeing "references available upon request" - because of course references should always be available upon request! I've shown this sheet to many employers and even to my references (so they know how they are described), and they all agree that it's a useful, thoughtful way to present references. It works for me!
