[Not indefinitely. Make no attempt to look for work and it will (and should) stop. That has *always* been the rule, by the way, it just wasn't properly enforced. ]
Actually, that is not true for everyone (it is possible to negotiate a JS Agreement, containing many possibilities and omissions), but, for the majority, yes, you are correct.
BTW ... what would you except that the person will then do? Get a job? ;)
[It is reasonable to expect everyone of approipriate age and state of health to work]Possibly reasonable, just impossible.
["On the dole" can mean different things to different people.]That is why, anyone with any real understanding, does not use the term.
[What a wonderful way you have of looking at life.]Owning one's home is only a recent development, in the UK, for the majority (and not the norm, in others, right now) - it is also an impossibility, in a Capitalist system, as you can see, right now.
[e. It'ssupposed to be a way of tiding one over whilst looking for work. Not looking for work whilst "on the dole" is a breach of contract. ]Presently, yes, well done, but it need not be the case ... what we have, now, is just PR to try and placate people like you.
When no work is possible, then JSA (plus associated benefits) is indefinite, and it cannot be anything else, if you wish to maintain a 'civilised' society.
