I work in IT, so it can vary, some weeks are slow and I only work 40. Some weeks are insane and I'll have to put in 50 or 55.

I don't know how people work 80hrs a week, I would lose my mind.

I meant in terms of working in a corporate environment. Obviously homemakers are "working" all the time, but it's not the same thing in the sense of working at a company, which I believe was implied by this post.

My husband works 40 hours a week and goes to school full time, online.  

He already has one Masters degree but needs another and full licensure to remain in his job.

For awhile, he had 3 jobs working about 60 hours a week.

As a mother who homeschools, I work all the time.  

Last year and especially near the end of the year I was at about 80 hours a week. I was exhausted a lot of the time. 44 hours at my regular job and around 40 hours at my online job.
That's six days a week from 7am to midnight with breaks in between.

This year is gonna be a little different come May I'm gonna cut back.

It's not very nice of me to say, "I'm glad I'm not the only one," because I wouldn't wish my grueling schedule on anyone.  It's just that I can say that I I know intimately how you feel.  Life's been brutal since August.  This year, I won't have much of a respite, because the current season (although down from 80 to 60) is scheduled to last until March or April.

I hesitate to bring up the dreaded V word (vaccines), but I'm considering them for the next work cycle, since the vulnerability of an over-fatigued body cannot be denied.  I don't have that much control over how much I can cut back, since I have an unusual level of skill and reputation for my industry (both a blessing and a curse, obviously), and I am only somewhat/sometimes a free-lancer.  I also work for companies; they control me more.
