This form is only for employees who use a company domain email that has already been registered by their employer with AnOliveBranch.com as a ‘Registered Permitted Domain’. The 'domain' is that part of the email address after the symbol @. For example, in an email address 'name@company.com', the domain is 'company.com'.
For employees who use non-company domain email addresses (e.g. a private/personal email account such as, say, Gmail or Hotmail or similar), you cannot register yourself here. In that case you must be registered by your employer.
