I work 40 hrs a week as well, in the insurance field. Have been working for the same company 18 years. I have missed work 3 times (3 hospital stays), and occasionally 1-2 days when I'm not feeling well.
Lately it is starting to get harder and harder to sit in an office for so many hours, and I would be really grateful if I didn't work. But, I need my insurance, plus I want to pay off a loan I have, so I'm being patient....
I like working, but at this point, the ideal would be 4 hrs a day, and then go home and have a nap....
I wish I was healthy and could work for 20 hrs.....
