Some free advice.
See if you can't find another job before leaving your present job. (It's always easier to find a job if you already have one.)
that is true. Although i don't know why people without job is harder to find a job than people with job, it is still the fact. It sounds to me like most of the employers have a bias to the jobless interviewee. To some extend, i could understand why. Perhaps they thought that those jobless interviewee are mainly quit his/her previous position because of incompetency, or being fired by his/her previous employer.
Employers have a bias toward people who are already employed. If someone has a job that shows that he is employable.
Any input is highly appreciated
