Would you ask to see a reference before someone submits it?
If someone wrote you a reference and it had to be sent via mail to the employer requesting. Would you ask to see it first? Do you think if the reference was late and you were sent a copy via email. Do you think it would be appropriate to send it to the potential employer via email on behalf of the person writing because they haven't gotten around to sending it snail mail? Then telling the potential employer that the original is coming.
