From LOA 25:
When an Integrated Seniority List is presented to the Company that satisfies the terms of Section 5 of the Transition and Process Agreement (“TPA”), pilots who are or previously were furloughed shall receive additional pay longevity credit for all time spent on furlough provided that they have additional time on furlough which was not credited for pay longevity purposes upon date of signing, and provided further that the application of such additional credit does not result in any s-United pilot having a pay longevity date that is earlier than the pay longevity date of the next most senior s-Continental pilot.........

I don't think YOU are getting it. The after SLI adjustment is for time spent on furlough. Nobody's ACTIVE service is getting wacked after SLI. Your're additonal credit can be 0, but not negative.
