I have created a program that allows the user to view/add/delete employees and also view employee payslip either weekly employee or monthly employee and this is all done in the console. My programme runs fine and does as asked but it is not OOP I feel. Can anyone suggest any changes to make it more OO.

Please see the 5 classes below that I use.
