Well I don't know about the whole not working thing but if the sabbath is used to spend time with God and develop the relationship then everyday is the Sabbath for me. Why on earth would I set aside one day of the week to spend personal intimate time with him when I can do this everyday? No matter what I am doing or where I am I can always find him I can speak with him I can connect intimately with him and I can learn from him. When People make the excuse that they don't have enough time to spend with him they are lying to themselves, if you love someone enough you always make time for them.
No you don't, sorry but you can't, 6 days a week we have duties, work things that need to be done. while you may have time with God and worship Him everyday, The Sabbath is different because its time without distraction. and in the end its the only day God blessed and made Holy, so it is not like every other day unless you make what God makes holy common.
