In addition to the other advice you've gotten: §23.Q.6.c.Exception: is the contractual reference for this. Note the language is slightly sloppy wrt 2nd-day coverage under the new contract--instead of "same day," it should read (and has been applied as if it reads), "same day or next day"--i.e., if you have a RES assignment for the next day or 2nd day, a GS for current or next day is NOT a GSWC, it's applied "without regard" to any such RES assignment.
