If you are unable to add staff to ShiftCare, it may be because the staff has an existing account with another organisation that uses ShiftCare. ShiftCare can handle one email/roster per person, therefore, you cannot use the same email id for the one staff member.
If it is an email duplication then, you will see below message on the screen while adding a staff.
There are two solutions to this:
1. You can request your staff to create a different email ID or
2. You can make an alias email for the staff. An email alias is simply a forwarding email address. Another term often used to indicate a specific mode of email forwarding is 'alias expansion'. As a result the term 'email alias' becomes more generic and relates to an address forwarded in a simplistic fashion.
Note: If you wish to go ahead with the second option, please notify your staff about their email alias as they will need to use this in order to log in to your organisation's ShiftCare account. This means for your organisation they will log in using email alias firstname.lastname@example.org and for the other organisation they work they will use their staff email email@example.com.
Staff can keep the same password for both logins if they wish.
Yahoo email addresses
Yahoo manages email aliases in a different way to Gmail and other email providers. To achieve the same thing Yahoo provides these instructions on how to create or delete an email alias in Yahoo Mail.
