These structures have a maximum worker capacity at a certain limit. Anyone can employ their workers here, as well as buy buildings or put them up for sale.

Building owners earn returns based on the workers employed on a daily basis.

Workers, on the other hand, can earn as many rewards as the worker they employ according to the rewards given by the buildings.

The buildings have a maximum capacity and when they are full, no more workers can be employed.

Users can withdraw their workers from work at any time.
