This means that you will be held in jail for up to 90 days without the right to bail. The prosecutor must ask for a bail revocation at your first court hearing on the new case. The judge on the new case will then make a decision on whether to hold you without bail and set a bail on the new case.
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.
