Dear Chris,

We are afraid that the schedule of all temporary security guards will be fully occupied by the end of the year, can you please confirm the person who will be on duty on 17[SUP]th[/SUP] December as soon as possible? Otherwise, we will find it ourselves. Thank you.

Best Regards,
Daniel

Is the second sentence related to this first? To me, they do not seem to be related.
