Usually such a requirement is handled by Chain of Command Design Pattern.

I believe a value to the 'supervisor' or 'senior' in the employee would solve this problem. An interface that would have a few methods to 'forwardCall(Employee.Supervisor emp)' would make things look better.

public class Employee implements Call{
Employee supervisor;
String fName;
String lName;
...
public Employee(String fName, String lName, Employee supervisor)
{ this.fName = fName; this.lName = lName;  this.supervisor = supervisor;}

public transferToSupervisor(Employee sup)
{
	//Code to transfer call
}

public interface Call{

public void answerCall();
...
public void transferToSupervisor(Employee supervisor);
}

Not sure about this answer, feedback appreciated.
