Nick, sounds like you just need to man up and dole out the assignments. I've always really hated managers who try that "getting people to volunteer" as it just means that the one hard working responsible guy does all the OT.

The way I would handle these spots when I was managing is to gather the guys together and say "look we're going to have to do some OT in the next few weeks, so let's work out who wants which shift". Then I would usually give the guys the pick of the shifts they want and I would cover the one nobody wanted.
