I don't know if it's just me, but for the life off me I can't understand the attitude of those that think of attending a fitness test or CCS as such a huge chore they need to look for ways of avoiding it. They aren't going to stop you leaving if you fail so what's the problem. Do it a bit early to avoid clashes with resettlement activities.
I think it's more the principle of being made to run between 2 lines to ensure you are fit to do your job(even though this is Bo**ocks) even when you are leaving and no longer need/want/are in the job for which you are jumping through nonsense hoops.
