CN is coverage day, PN is pairing not bid.
So CN is basically: "we deemed the 11th of September a coverage day and you didn't bid any trips that work that day. Therefore you're losing the 4 day crediting 26 hours starting on Sept 12th for a 5 hour standup starting on the 11th"
PN is" we couldn't complete your line based on your bid so we just gave you some random crap leftover"
PN is your fault, CN is just absolute crap that is just the result of our "globalized PBS".
How come the guy below me got the 11th off and I couldn't? Globalized pbs baby.
