The issue of seniority will divide the crew full stop. There are a lot at the bottom who see no chance of ever moving up the list due to the way the company is going. Whether these directions are right or wrong, whether the government is right or wrong, we just have to adapt and move with the times.
With the current threat of new type flying going to others, it could be we will not see the 380 and possibly not LA in the coming years. But do we have to protect the senior at all costs in everything we do? Again not my thought, but you don't have to be einstein to know that this is the feeling among many regulars to certain destinations the LA people only ever see on reserve.
Once again, a united front will require all looking out for each other. The senior people may have to give a little to support the junior crew, and the reverse will also happen. Without this, the bigger enemy will tear us apart.
