Imagine a company with 3200 baristers or 2779 junior accountants. How would the promotions go then? Can you imagine a "barister check day" every six months with a medical thrown in.
Lets see, what would I do to advance my position? I know i'm not as good as Nigel there, but if I, well, get out my knee pads, yea, thats the ticket! maybe kiss a little arse, yea, i like the idea!
No one is perfect no matter how much you think you are. We all have good and bad days. some sim sessions will be good, some not so good. You may be an excellent pilot but have a short temper. You may get along with everyone, have excellent CRM skills, but be an average pilot.
Seniority is what we have because we have a lot of folks doing the same job, many hired on the same day. We need a system, and this works. Training and sim checks is our way of weeding out the chafe. Are we going to have a "fly off" in the case of a tie in our training scores?
OK, time to get the day started!
