Barry, reading your reply to me, thought it better to illuminate a little.
People signing on have a contract with the Jobcentre. They MUST be looking for fulltime employment, must prove it, and, after six weeks, must be enroled with at least 2 work agencies.
They are also required to be enroled with a number of online jobsites. The search radius for unemployed resident in Dover reaches as far as Ramsgate, Canterbury and Hythe.
This is the radius within which one must look for work.
I've noticed that a number of posters on the Forum have very vague ideas of what signing on implies. You are one of them, Barry!
