You're probably thinking more of fiancee visa refusals.

Being a spouse naturally suggests that your intentions are more serious.

I can't see any reason (as a spouse joining your husband) why the ECO would want to know anything about YOUR finances or employment situation back in the Phils.

By all means keep your job open, but no need to even mention it to the ECO.
Doing that WILL only complicate things unnecessarily.

This is just my opinion.
