Why do my Shift Assignments keep turning Inactive?

A Shift Assignment changes to Inactive by itself when its End Date has passed. If you set it back to Active and it flips again, the End Date is still in the past, or another active assignment overlaps it.

What you see

• A Shift Assignment that was Active now shows Inactive in the list, and you did not cancel it.
• You change Status to Active, and the next day it is Inactive again.
• You get this error when you try to reactivate it:

Employee Arjun Reddy already has an active Shift General Shift: HR-SHA-2026-00012 that overlaps within this period.

• The employee's check-ins no longer get a shift, so they are marked Off-shift, and auto attendance skips them.

Why this happens

A Shift Assignment tells the system which shift an employee works from the Start Date to the End Date. Status shows if the assignment is in use. Only Active assignments are used to find the employee's shift.

A scheduled job runs once a day. It finds every submitted Shift Assignment that is Active and has an End Date before yesterday, and sets Status to Inactive. A Shift Assignment with a blank End Date is never changed by this job.

When you set Status back to Active on an old assignment, the End Date is still in the past. The job finds it again on its next run and sets it to Inactive.

Overlap is the second cause. The system does not allow two Active assignments for the same employee on the same dates if the shift timings overlap. So the system stops you from setting Status to Active when a newer assignment already covers the same dates. By default, it also stops two assignments on the same date, even when the timings do not overlap. Allow this in HR Settings with Allow Multiple Shift Assignments for Same Date.

Assignments can also have an End Date you did not type:

• When a Shift Request is approved, the assignment ends on the request's To Date.
• A Shift Schedule Assignment creates assignments for the days of the schedule. If you do not give an end date, it creates them for the next 90 days.

For example, Vikram Desai at Bluepeak Technologies assigns General Shift to Sneha Iyer from 1 July 2026 to 30 September 2026. On 2 October, the job sets this assignment to Inactive. Sneha's check-ins on 5 October have no shift. If Vikram only sets Status to Active, the job reverts it the next day.

How to fix it

1. Go to Shift Assignment and open the Inactive assignment.
2. Look at End Date. If it is in the past, this is the cause.
3. Change End Date to a future date. To make the assignment open-ended, clear the End Date.
4. Set Status to Active.
5. Click Update.
6. If you see the error Overlapping Shifts, open the assignment named in the error. Either change its End Date to the day before this assignment starts, or set its Status to Inactive. Then repeat steps 3 to 5.

If you only need a new shift from today, create a new Shift Assignment instead of changing an old one. This keeps the shift history for past attendance.

How to prevent it

• Leave End Date blank for employees who work the same shift all the time.
• Before a long assignment ends, extend its End Date or create the next one.
• For rotating shifts, set an end date on the Shift Schedule Assignment that covers the whole period, so assignments do not stop after 90 days.
• To see assignments that will end soon, open the Shift Assignment list and filter End Date for the next 30 days.
