A surgeon or any other professional does not base his pay, vacation and bidding based on senority. Pilots do and hence a senority list.
The reason the industry sucks besides us pilots being complete tossers is airlines don't have to pay market rates or industry standard when they can just bring a DEC in from a ****e company (jumping the senority list) and pay him less than Market Rates.
Good airlines' pilots have figured this out and ban DECs for very good reasons. Besides the ethical issues they suppress wages.
Having a look back at EK one will also notice the company does not save any training costs if they have that much of a failure rate and require additional training.
Does anyone know if TCAS buddies are looking for a job? We all know that EK does not need any DECs so one has to wonder why EK is bringing in the DECs. TCAS would know.
