Please follow, this employee was hired in 1990 in PA as a PT, Than he transferred to AZ as a PT in 1998. in 2003 this employee made a transfer as PT to a new hub that just opened that year (change of operations, seniority dovetailed ). Than in 2004 he made another transfer as a PT to another hub (no change of operations, just a normal transfer) in 2005 he went combo (same hub) and is been there ever since. I argue that his seniority is 2004 in this present hub! This employee argues his seniority is 1998 when he transferred from PA to AZ, is he right??
