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.
After an arrest in Pennsylvania, a criminal defendant is taken before a Magisterial District Judge (MDJ) who sets the bail amount. If the defendant pays the bail amount or uses a bail bond service, he or she will be released from jail while awaiting further developments in the case.
