It's widely recognised that employee referrals can be vital recruitment channel - delivering candidates at a lower cost who are likely to stay with the organisation longer and reinforce the referring employee's commitment and therefore retention. 

But many organisations steer away from referrals through fear of them cloning the existing workforce and - if it's not as representative as the employer would like - impacting on diversity. Whilst this is clearly the case, it can be mitigated through ensuring job opportunities are visible across other channels or upweighting referral payments for under-represented groups - as Intel do.
