Well you can take it for whatever you want, but there's no blanket answer, you know your relationship and what it can handle. Mine has never been better and we've been together 18 years, I've been at UPS for 5 and change. If some awkward hours will ruin your relationship than maybe it's not built on the foundation you think it is. This place can deliver a stable income, great benefits, and a quality of life most Americans dream of, but never attain. You can adjust your family habits to accommodate just about anything, the hours aren't that terrible most of the time. There's no outrageous difference in rate of divorce over any other profession.
You do you baby girl. If making sandwiches is better for your relationship than that's what it is. Good luck.
