While I understand your feelings regarding training, please have some consideration for the trainees already in the system. They have been sitting around since January, getting very bored, through no fault of their own. Remember the very human aspect to your action. You may be affecting the people who could either help you get your leave, early retirement or even get a more reasonable break or even open sector 33! (I know the last is very implausable).
It isn't a matter of black and white.
