Define a subclass of Employee called Worker. A worker has a manager $($who is another employee$)$ and this manager is given as an argument to the constructor.

Define a method in Worker

get$\_$manager$($self$)->$ Employee

that returns the worker's manager.

Define a subclass of Employee called Executive. An executive has a yearly bonus in addition to a wage and this bonus is given as an argument to the constructor.

Override the Employee.wage method to take a bonus into account. You must call Employee.wage from Executive.wage$($using super$).$ Remember the existing wage method calculates a fortnightly pay, but the bonus is annual.
