Family Issues
I would like to address the statement regarding family sacrifices. It may never be worth it. To me, it is a decision, not so much a sacrifice. When one decides to make aviation a career, for the most part, we have made a choice that can have negative effects on family life, relationships with wives, and on our ability to have roots in a particular place.
Throughout my career, many of my friends were envious of all the places I got to go, the people I met, the adventureous nature of it all. They grew up and lived in one city for most of their lives near their extended families. They had generational roots there and I envied them for the stability they seem to have and strength of family support.
There we all were looking at the others life with envy. The point here is that it was a decision made. To find the balance in the middle, well, that is the hard part. In the end, we have to set the priorities we have and decide what is best. True sacrifice is the giving or surrendering for anothers benefit. Your children did not vote to sacrifice but you and your husband decided that this was a course of action to something that would reward you and him together I assume.
If you want my empathy, then show some empathy for others who make these same kind of decisions all the time. TA's come and go and they are usually result in a vote. If you vote No, that is your right. My problem has been your arguments do not hold true in the real world and unless you understand the other side's position and are empathetic with them, you will never reach a contract that is acceptable to both sides.
Unless you all can find a common ground of all parties, the decision you and your husband made will remain full of angst that will effect those who are the priorities of your life-- your children.
