its all a guessing game at this point. some larger k routes could possibly be cut to a 4 day week with the rca still working a day each week. others may drop into the j day slot will rca's working one day every other week. small k's , j's, and h's may not have any weekly days off. being laid off shouldn't be a concern. part of giving up benefits for rca's years ago, was being able to have a sub for each route. - regardless of how many days they would be able to work.
it might not be a bad time to move up quickly as no doubt some will become discouraged, and quit on their own - leaving more work for those that are left, as well as a choice of more routes. there will always be the vacation and sick days to cover. unless you have more subs then routes, your job should be safe.
