This post is mainly aimed at Speed, Pronto and anyone else who regularly posts work on other exchange sites (CX etc).
I'm interested to know when you post work are you normally getting it covered with guys you know and have used before or is it quite regularly that you're picking up new drivers?
Basically what I'm interested in is the split between using X exchange to simply alert your regular guys of work you need covering vs using the exchange as a recruitment tool.
