What do you think if I told you that I'm going to walk out on my job?
That sounds drastic. What would happen if you did that?
I don't care if it's drastic. I would look for another job.
You should never walk out on a job. It's always proper to at least put in your two week notice.
I don't care if it's not proper. I can't stand being here a second longer.
I understand you are feeling frustrated by your job, but quitting without giving notice can have an impact on your future job opportunities. If a future employer contacts your current employer, it's likely they will be told that you quit without giving any notice. That will hurt your chances of being hired.
