Add more employees.
It is very common for object-oriented programs to create more objects as the program runs. The new objects might be needed to handle additional data that the program needs to work with. The picture shows your business after adding a few more employees.
Notice that objects (workers) can communicate with
each other,
not just with main()
(the boss.)
Some objects do not communicate with main()
at all,
but communicate only with other objects in the system.
