Professional work references typically come from direct supervisors, general managers, or co-workers.
Direct supervisors often give the best recommendations because of how well they know their employees. For instance, they’re likely able to provide specific examples of your work performance or attitude.
In any case, choose someone with whom you’ve worked directly and formed a good relationship.
For personal references, use someone who you've known for at least one to two years and who can speak to your character. Many people use family members, close friends, or neighbors as personal references.
Remember to ask if someone will be your reference before you add their name to your Reference List. It’s important to give them a heads-up so that they can prepare talking points. To that end, you could also ask for a Letter of Recommendation with clear examples of your skills and accomplishments.
