Don't get too far ahead of yourself. I saw a month of NQAT completely disappear when returning from leave and they found me a slot beginning on the very first day of availability I provided. Hopefully yours sticks, but it would appear that NQAT can also be a placeholder while the training schedulers flow things out in the days immediately following your return notification. If it's been some time since you notified them, your odds of keeping the time off are probably better. Please keep us posted how this plays out!
