Users mark their daily attendance in the shipping service system to record their working hours accurately and maintain accountability. The system tracks attendance for each working day and stores the data securely for reporting and operational purposes. Users are required to mark attendance regularly, as it helps manage workforce availability, assign daily shipping tasks, and ensure smooth operations. In case a user is unable to attend work on a working day, they can apply for leave through the system by selecting the date and providing a valid reason. Leave requests are reviewed and approved by management, and approved leave is reflected in the attendance records. This process helps maintain transparency, improves productivity, supports proper workforce planning, and ensures uninterrupted shipping services.
