Ask Your References Before an Employer Calls
Give each reference enough context to speak accurately about your work.

A reference should not learn about your job search from a surprise call. Ask permission, confirm contact details and explain which kind of work you are pursuing.
Choose knowledge over status
A person who directly observed your work may provide more useful detail than someone with an impressive title who barely knows you. Consider former supervisors, project leaders or other appropriate professional contacts. Follow the employer’s requirements about the types of references they accept.
“I’m applying for customer support positions and would like to ask whether you would be comfortable serving as a reference. You supervised my scheduling and service work. I can send the posting and my current résumé if that would help.”
Make preparation easy
Send a brief reminder of the work you did together and the role you are targeting. Do not write a script for them to repeat or ask them to confirm something untrue. Let them describe their own observations.
Confirm their preferred email or phone and how they want their title listed. Keep the reference document separate from your public résumé unless the application specifically asks otherwise.
Respect their time and privacy
Tell them when an employer may contact them, if you know. Share their details only for the agreed purpose. After the process, send a short thank-you and an update.
If someone declines or seems uncomfortable, accept the answer and choose another appropriate contact. A willing reference with relevant examples is more valuable than a reluctant person who feels obligated to help.
