Design and develop a web-based Employee Management System with integrated Time Tracking functionality. The system should allow users to manage employee information, including personal details, job roles, and performance reviews. The time tracking feature should enable employees to clock in/out, view their time sheets, and submit them for approval. The system should also provide reporting capabilities to track employee hours, attendance, and performance. Focus on user-friendly design, data security, and scalability for a growing organization. Ensure compliance with data protection regulations and provide responsive design for various devices.
