cachsux is right. No way would I ever go back to package car, and I know of no feeder driver that would, regardless of what that guy was saying last week about feeder drivers going back to PC. Not happening. Feeders is much easier than package car, physically. It is way easier to work more hours back here than it is in PC. And it takes more than a week to get comfortable, but it does get easier to drive this equipment. Since I came back here two years ago, the push for production has spiked. Now, that's no different than PC, meaning it's up to you to fight it off. You can't rush things back here, because if you make a mistake, you can't say you were rushed. And mistakes in feeders can have serious consequences.
Only you can answer the questions about how your family will respond to this job. My kids are almost out of the house now, and I work nights, so for me, it's not really an issue for me. As far as working nights, as long as you can sleep during the day, you should get used to it.
