👨‍💼 Employee Management System

A menu-driven Employee Management System developed using Python Object-Oriented Programming (OOP) and File Handling. This application allows users to manage employee records with features like adding, updating, deleting, searching, and viewing employee details.

The application automatically:

• Loads employee data when the program starts.
• Saves updated data after every Add, Update, or Delete operation.
