No, and here's why: because both are doing the exact same job. what difference does it make to the building owner how much experience the guy had as long as the job is done right?
Same thing with pilots. I have never understood the longevity pay scale. Two 737 pilots, one a 12 year FO and the other a 2 year FO, are doing the exact same job. Why does that 12 year FO deserve more money? Conversely, why does that 2 year FO deserve less money. At the end of the day, both are doing he the exact same job: moving the airplane from A to B. Eliminate longevity based pay, pay all pilots in the same equipment and seat the same, and you do two things: 1) eliminate management's tool of shifting flying from one carrier to another because the other carrier has less senior pilots, and 2) minimze the pain felt by pilots who have to switch jobs after 5 or 10 years. Much more effective and easier to get than an NSL
