If you receive a shift invite it means the employer has specifically invited you to work that shift. By selecting ‘view’ on the invite, this will bring up more information about the shift. If you click 'Accept Invite' you will be automatically and instantly accepted for the shift without having to wait for the employer to approve your application.
If you're unavailable, simply click ‘reject’, and the home will be notified that you are unable to work.
Keep in mind that the client may have invited a number of nurses to the shift which means that if you are confident that you can do the shift you should accept the invite as soon as possible to avoid missing out.
