related Must one "work" and "deserve" to observe Shabbat?
Why don't we have to work every non-Shabbos day?
Is there any source which explains that the phrase lo ta'aseh kol melacha points exclusively to the seventh day and therefore means that on other days we must perform some sort of melacha? (that the cessation is unique to Shabbat)
This position might say that "sheshet yamim ta'avodu" requires that the other days not be Shabbat in a way similar to the statement that "beini uvein b'ney Yisrael" demands that others not observe Shabbat.
Other questions have mentioned that there is some sort of expectation (according to some) that one be employed, but is there a source that focuses on the halachic concepts of work and cessation from work?
