I hear what you saying. F/O's especially must be very worried, despite what the letter says. As a Capt myself, and obviously being an F/O once, I can see the points issued. It happened to me too. Unfortunately, according to the letter you all got, it is happenning, or going to happen. As I see it, you don't have enough suitable F/O's, even if they joined last week, therefore, you don't have enough Capt's. Your manual restricts any up-grade for 3 yrs, and even accelerated to 18 months. It's definately not fair, IF you do get superceded by a DEC.
