Ah Carolyn, working on Saturday AND holidays is the reason I moved on from newspaper work.  It is also the time frame I see my husband working in academia: morning, noon, night, holidays and weekends.  Law, business owner, medicine, teaching – they all seem to require a week far greater than a 40 hour week.  I'm not sure how one avoids this unless you take a 40-hour-a-week job and abide by the limits. The Saturday work to make up for a holiday is hard to swallow, but in our culture we do it all the time and do not always recognize that we do it.
