Have you never had any contact with "temp" workers in what you do Roland?

It is quite common for them to confirm attendance and then not do so.
They wouldn't get a second chance, in any of the lines of work I've
been involved in.

But if the job needs doing, you have to employ them if there are no
others with the required skills or availability (at least until such a
time as you can recruit full-time staff).

I would cast my net wider.
