Time and Attendance
sThe Integrated Time and Attendance System (commonly known as ITAS) is IHS’s time and attendance system. It records employees’ work schedules, additional hours worked, and all leave requests. It is important that all timekeeping information is correctly maintained and reviewed in ITAS by employees, timekeepers/Administrative Officers and leave approving officials since the information in ITAS directly affects employees’ compensation.
