I PVR'd in 2011 with a firm offer of a job in place. My future employer required me to start work within 4 weeks. After speaking to my deskie, he said not a chance and that the waiting time was 6 months (I was FC). After relaying this to my SO1, he then spoke to the same deskie...within 24hrs I was informed that I could exit once all my clearances had been completed (and provided the SO1 was willing to absorb the gap). Needless to say (and with a heavy heart) I left - it took no longer than 2 weeks from the point of pressing the button to walking out the door!!
