I'm gonna ask my boss for some days off work and then quit after he gives them to me.
Why would you quit after taking time off?
First off, I wanted to know if they'd give them to me. Second, I don't want to work here.
You should always give proper notice when leaving a job. If not, your work ethic will be questioned by future employers if they see that you left without notice.
It's an easy way out of the job.
You're ruining references you could potentially use in the future for another job. Just quit the job in an honest way.
