Its written on the form where and how to send it. Just send via internal mail - red box after security on 1st floor, or beside mailboxes on Ground floor. It has to be clearly addressed to them as written on the form page 2, otherwise it might never make it. Ironically they have lost my documents twice, but both times they acknowledged they lost them after receiving them
Rim-job, there is no scanning of docs, you just have to fill out the basic info on HR direct and then send the original forms, invoices the conventional way anyway. Why it makes much of a difference that we complete that 5 minute process ourselves, I have no idea. If it was all scanned and there was no hard copy crap then it would make a lot more sense!
