4 day work week

Several states have businesses looking at a 4-day work week, including Birmingham, Alabama. A recent news report indicated that due to high gas prices and energy prices, companies were seriously considering 4-day work weeks for employees. Some schools have already adopted this policy in northern states where the weather is more frigid. The new work hours would be 8am – 6pm versus the 9am – 5pm work week. My question, Madison County, is do you take Friday as the third day or Monday? Sure makes for interesting conversation.
