Question on seniority number... Does hire date come into play at all, or is it solely based on last four? For example, if there's a class with 1 Jan and 2 Jan hires, and the 1 Jan's last four is 0000, and theres a 2 Jan hire with a last four of 9999, does the 1 Jan person get a higher seniority number than the 2 Jan person? Or is it just based on last four? Thanks!
