In Europe, Middle East, America and Australia, the normal working days are only 5 days a week. Some of them use flextime and works on weekends. I personally want that our working days should only be 5 days a week for all private companies. They can extend on weekends by doing shifts for all I care. I'm been working on private companies before for 6 days a week and I still don't like the idea of a rest day which is a Sunday only.
So, I totally agree with Cong. Tom to have an 8-day holiday in December. So what if we have a lot of holidays. We are not getting richer anyway but the capitalist.
Don't ever believe that the capitalist losses a lot money for working only 5 days a week. Their losses wouldn't make them poor like us.
