Depending on the size of the organisation or how it's funded if it's public sector, then it may well be the "restructuring" that's holding it up - and by that, I mean there are probably teams and managers screaming out for funded posts to be filled, but a blanket ban on recruitment may be in force while someone with a fancy title figures out the shit state of their staffing affairs.

I've had times when I've had 40% of my team's positions open, and when I've asked for authority to recruit for already funded posts (probably for budget reasons), I've been knocked back because "nah fuck you, we're waiting on the staffing review being completed". I don't really give a fuck about the future plans, I'm wanting to recruit for the posts we have now!

It's frustrating friend. Shit doesn't make sense.
