Type training vs Loyalty
It seems as though in average aviation career one has to change type rating four or five times as airlines re-equip the fleets.
Management will lie through their teeth about 'internal promotions', 'upgrades', etc when they change fleet. It often results in trading a command position for a right seat on a new aircraft. The excuse that they have to initially employ rated crews to establish the operation is also often grossly exagerrated.
The beancounters have decreed that training is an unnecessary expense when it is easier to poach type rated crews from other companies.
