First -- Don't sell. That is something you can pass onto your children.
Next, ask your husband what his work schedule is. Perhaps he replies, "Honey, you know I get up at 6:00am and am on my way to work at 7:00am and I am home by 6:00pm. You know this. Why are you asking?"
Then you can tell him what YOUR work schedule is: "I was just curious because I think maybe you didn't know I have THE EXACT SAME WORK SCHEDULE. I am at work-work for 4-5 hours and am doing my "other" job for 6 or more hours. But as of 6:00pm, both of us are technically off-the clock."
Let him know that once dinner is on the table, all off-the-clock work will be shared so that there is:
1.) shared housework (dishes, baths, laundry, yard work, taking out the garbage)
2.) shared family time (playing a board game, taking a walk, doing homework)
3.) shared adult time (watching a moving, playing cards, canoodling)
4.) shared ALONE time (music for you or golf for him, etc.)
It is your job to tell him this is important to you and it is both your responsibilities to make the extra time happen.
