If he/she is indeed a current indeterminate employee, then the full Relocation Directive has to be offered along with the LoO. Otherwise if he/she is a casual/term employee appointed to another term then it has to be negotiate (1.4.3).

full-time and part-time indeterminate employees; or
part-time employees appointed to full-time indeterminate positions; or
