That's one of the points of user_u, it can't get to root   :)

staff_u can get to sysadm_t (through sudo) which then has most admin
privs.  Although I beleive dwalsh would suggest staff_u -> unconfined_t
via sudo if you want an admin user.  (which would require adding
unconfined_r to staff_u I believe)
