I got this from other visa site:

" "...For the purposes of these Rules, a person is not to be regard as having (or potentially having) recourse to public funds merely because he is (or will be) reliant in whole or in part on public funds provided to his sponsor, unless, as a result of his presence in the United Kingdom, the sponsor is (or would be) entitled to increased or additional public funds..."

This is taken to mean that the UK sponsor can be in receipt of public funds, but must show that the applicant will not cause the sponsor to receive additional public funds."

But ... maybe its better to wait till there's a new job. Better to be honest and don't withhold informations cause it might lead to worse situation.
