Okay Welfarite and thanks again for your reply it seems clear enough now,however,
if a person were to become incapable of work because of a broken leg,for instance then this means that,
1) They would be no longer able to seek work because of their current disability
2) If they are currently caliming JA they no longer satisfy the criteria for claiming their payment as they are not actively able bodied to do work or seek employment
3) And by inference to the above payment would stop and that person is effectively unpaid, disabled (albeit for a couple of months at most) but technically not unemployed?
