Husband’s job

So….i was in my third trimester when my husband first changed to a new job. It has been 7 months in the new job (with me returning to my work in a hospital, non-shift)…… Today, he asked me about my thoughts about shift work, and expressed his interest (60-70%) towards applying and trying to train as an air traffic controller, as he is not happy with his current workplace (cited reasons such as hustling, not having mentors)…… Pay cut and shift work aside, I am struggling to know how to support him, as I am once again wondering if he thought about the impact on the family…….. What should I do?
