If you're employing a temp or volunteer, in fact anyone not on the CBH payroll, you have to get them to complete and sign a Third Party Agreement (TPA) - the form is linked to from this article.
PLEASE NOTE this is addition to the New Starter form
We can't even request a new user set up until CBC ICT have approved the TPA so it needs to be submitted as a matter of urgency if you're employing someone 'off payroll'.
You can only request a maximum of three months IT access at a time (although you can request up to ten additional days in the additional time section if the contract only overuns the 3 months by a small margin - you can't use it to request substantially more than 3 months) and you should submit a new form at least a week before the existing access runs out
