If you are saying it is a 2 Rural Route office with only 1 K route you should not be formula.
I’m rereading the originsl post (again!) and I’m thinking it’s NOT a two route office—there’s more than two routes, but after invoking the formula, there’s a J route and there’s a K route both with Saturday relief days (and the other routes have non-Saturday relief days).
ok, according to the implementation guidelines, no other day of the week can have more carriers assigned that as their relief than Saturday—that is, you can’t have two K routes assigned Monday as a relief day while only one K route has a Saturday relief day (Remember, the formula involves reassigning the relief days of K routes only). Saturday relief days have to exceed or equal the assigned relief days of the rest of the week.
My point is, you can’t have zero K routes with a Saturday relief day. There has to be at least one, and no other day of the week can have more than Saturday has.
While a J route carrier cannot be reassigned to a non-Saturday relief day, the Order of Consideration applies when covering a route. if the K route with the Saturday relief day has not signed the RDWL,
and is senior to the J route carrier, the J route will be required to work the Saturday. The J route’s relief day does not change and they will be compensated for working their relief day.
ETA: it does not matter* to which route the available RCA is primary for—they would have to work where they are needed according to the Order of Consideration.
*It
might matter if the RCA is brand new and not trained on the other route but in that case the RCA needs to be trained on the other route ASAP.
