I absolutely get why that would be useful to a prospective employee. But I cannot understand how it would work in practice: - Your former employer is giving out your contact information so you can help them recruit(?) - Your former employer is asking you to essentially work for free - But if your former employer offers you compensation now your opinion is biased - You may have liability issues (e.g. you say something unfavorable OR favorable, and you can be sued by the perspective employee or former employer) Rachel Nabors on twitter said it worked in the past, and I won't discount her experiences. I am genuinely curious to understand how the former employer arranged that with a former employee though.
