COMPLEX benefit rules can make it difficult to work out whether you will be better off taking a particular job, increasing your hours or moving employer. (‘Broken benefits system’, Oxford Mail, February 28) Oxford Citizens Advice Bureau and other local advice agencies can help check calculations.

Oxford CAB’s drop-in service is available at our offices from Monday to Wednesday and on Friday, from 10am to 1pm, and on Thursday from 10am until 4pm. Or call us on 08444 111 444 from 10am until 4pm, or see adviceguide.org.uk for more general information.
