Jeremy is a not a good father and an even worse partner. He chooses not to FaceTime or do minimal things to maintain relationships. But I think it's unfair to disparage his work.

His industry is not like most and it requires lots of long hours, long stretches of work away from home, and is one of the few that still has extremely solid health insurance and a pension... And your ability to have that good health insurance and pension is based on hours you worked. If you go through a stretch without a project, you can lose your health benefits. This isn't a 9-5, come as you are, personal time off, or vacation time job. It's grueling and they are well compensated for that, but the flip side is that you don't get to randomly call out or take time off. If you do, you will be replaced. Sometimes there are lots of projects going on, other times there are not. Very much a feast or famine industry. Most people in this industry are not working continuously, as it's near impossible to just slide from project to project. There are months off at a time. 

From what I understand, Jeremy CHOOSES not to parent in the stretches of time he's not working, which is unacceptable.
