To silent handover;
Congrats on your course and all the best with it.
Tell me, have you had any gaurantees re - your current post, ie, will it still be there should you fail, will you go to your current unit if you pass?
I have found nothing but 100% support at unit level, but little or non from NATS itself with the prospect of no job if I failed, or a 'posting somewhere, maybe' at best, succesfully putting me off.
With a settled family to support and a reasonable salary with little responsibility as is, I have decided to stay put. For the moment.
Best of luck to you,
