4 Days 10 Hours ?

A lot of rural areas of US already practising this to cope and fight with the increasing price of petrol which overwhelming day after day. They changed their working day from 5-day to 4-day.
Could it possible ? A lot of you will ask...
They are working 10 hours for 4 days now instead of 8 hours for 5 days. So basically they save up one day-travel expense for petrol. I think this measure is very good, besides saving money for your petrol; may be you can do some part time to earn more to fight with inflation.
For Asian, it is not a problem at all for them to work long hours. For me, now I work about 10-12hours per day for 5 days weekly. So I will agree this implementation but somehow it is not possible for wafer fab. (can just making dream!~)
