Restaff → It is formed from "re-" (meaning again) and "staff" (from Old English "stæf", meaning a group of people or a staff). The word "restaff" means to staff again or to provide a new group of staff members.
Think of 'again' ('re-') and a 'group of people' ('staff') — that's why restaff means to provide a new group of staff members.
