After working a while, I've found down that my current job is not fit my expectation, and 'd like to resign from it

And my application for permanent RP is still in queue (~1000 before mine), and my RP already expired this September.
I am wondering how this resignation would affect the RP application if I submitted the additional documents related to this resignation? And in reverse, how the expiration of my RP affects on the process of becoming unemployed? (register as a job seeker in TE system, unemployment security, etc.)

Any suggestion is highly appreciated!
