My unit has started a policy of fail your pft once, you get retest.
Fail it again you go on 3 month warning order with having to do remedial PT everyday, you have to pass the pft twice in this time.
Still fail to pass it go on commanding offciers and get a 3 month warning order.
Still fail to pass it then pack your bags and your gone.
I'm sure there must be other units who already have this policy.
With the recent rise in recruitment, we can apparently afford to be much more ruthless with the salad dodgers, as there are plenty of people willing to take their place and put the effort in.
