Wow. That's an absolutely crushing burden.
Try talking to a professional software developer sometime; and don't be too hurt when she laughs in your face about "several hours a weekend," constituting a brutal workload.
Software developers always work 40 hours a week, minimum. On a "death march" during the last three to six weeks before a major deadline, they often work an additional 25-35 hours per week. Unlike many teachers, they aren't covered by contractual overtime [and they aren't covered by the wage law], which means not only do they not receive comp-time or time-and-a-half for working those extra hours, they aren't compensated for them at all. [And God help them if there's a major glitch post-release, when they may have to work literally around-the-clock to push out a hotfix to tens of thousands or millions of customers.]
Most sales people are paid only a fraction of the additional time they have to spend in travel. Yes, they pad their mileage and charges against per diems, and their employers let them get away with it because the padding amounts to pennies on the dollar, and we know it.
Trade surveys say that people in executive management and sole-proprietorship with time-in-service under 20 years spend an average of 52 hours per week on the job. That's more than an extra week of work every single month of the first two decades of their careers.
As I said in my original post: What you are complaining about is the price of being a college educated white collar professional. ALL PROFESSIONAL PEOPLE SPEND EXTRA HOURS ON THEIR JOBS ONCE THE WORK DAY ENDS.
You aren't being asked to do anything except what everyone else does. And you're only being asked to do it for 183-195 days per year.
I’ll say to you what I say to everyone who thinks teaching is an easy job: if it’s so easy, come do it. And keep doing it. Stick with it. Do it for 30 years. Come on, it’s a breeze. And we especially need people like you, who know everything.
