Not so fast.
A "new hire" is generally regarded to be someone on probation, which lasts a year. That would make "First Officer 5-24-04" a new hire until 5-23-05.
This all officially started on 5-19-05 when the two companies made the announcement that they would merge.
So, #22726 hired in 1987 (I don't believe any 1987 hires were ever furloughed) did indeed go behind a west "new hire."
Man, does your post reek of desperation! P3019 was 5 days away from a first year anniversary when the acquisition was announced. The transation, however, wasn't consummated until the following Sept 26, giving P3019 16 months on property.
In addition, you have yet to prove that east #22726 wasn't furloughed at the time.
