However, I saw, these workmen, who are divided into 4 groups of daily rota, respected scrupulously only two assignments : the 2.5 dd of sleep and of work...

The remainder of time was passed either in waking of relaxing rooms (or outside) with their eu-phased friends (which are in the same rota group) or pro-phased (the group which is in relaxing room while they are in waking room and vice versa), but never ana-phased friends (which sleep or work while they're waking up or relaxing).

I've learned it was possible to change group for various reasons, but it is a way of starting a new life, without moving ! It would seem that this system makes it possible in the Universal Republic to have a 4 times larger usage of the infrastructures than in countries where everyone sleeps and works at the same time...

Nevertheless the majority of these workmen dream of founding a family and to have a quadri-family house. While bi- or mono-family houses are restricted to those which progress in the hierarchy.
