Are there “seniority” lists for technicians, engineers, baggage handlers, loaders, fuelers, ticket sellers, marketing staff, caterers, dispatchers, cleaners, management, etc?
Yes! In the US anyway.
With the exception of 'management', which is the adversary of labour, and the really unskilled labour like caterers and cleaners, whom are normally contracted services, most of the groups you mentioned above are represented by unions which generally view seniority as a sacred cow.
Management does not like the seniority system because it removes the opportunity to whipsaw employees against each other.
Judging from the tone of your post, I'm guessing that you're either management or a management wannabe!
