At Disney World, we are always on the lookout for good people to become cast members. When we realized some of our best new cast members were referred by current cast members, we made a program out of it.
We had cards cast members could carry. If they ran into someone who gave great service, they could hand them a card with details about applying for a job at Disney.
This worked well because people who have a job, and are performing well at their job, are not actively looking for a job. And many people didn't think they could get a job at Disney. These referral cards took care of both of problems. Plus, cast members who brought in a certain number of referrals got to attend an awards dinner and receive recognition.
People who work at Disney help bring in the right kind of people. Your good employees want to bring in great people to keep the work environment enjoyable.
Every business ought to be ahead of the game. Get out in the community looking for the right people to fill your next opening.
