are registering a claim for out-of-work benefits such as Jobseeker's Allowance or Universal Credit.
have actively sought work in the past four weeks and are available to start work within the next two weeks.
are currently working part-time but are actively seeking a full-time position.
have been made redundant within the last twelve months and are currently retraining.
