Being held without bond means that the individual will be held in confinement without being given the opportunity to be bonded/bailed out of jail. The person will be held without bond until a motion for bond is drafted and filed by the attorney and a hearing is held in the court.
No - if you signed the bond it doesn't matter whether you have a job or not - or whether the bondsman asked you if you did. You are liable as surety on the bond - having a job or not has nothing to do with your liability. Sorry.
