Weekends should be three-day long

Do you think it is unfair that weeks are five-day long and weekends two-day long?

In fact the weeks are longer than weekends. If people work for 5 days and rest for 2, they will always tired.

Another cause is if we have a huge family and a lot of friends we can't see them all.

I strongly believe that weekends have to be larger, as long as weeks.
