Summary: Worker was terminated alert should trigger only to the employees who terminated after we open the cycle.
Worker was terminated alert should trigger only to the employees who terminated after we open the cycle.
If any employee terminated before worksheet opens to managers, then that employee will be ineligible to the plan and we don't require the alert (Worker was terminated) for ineligible employee.

We are having ineligible workers on worksheet, we don't want Worker was terminated alert on worksheet to ineligible workers.

If any employee terminated freshly after worksheet opens to managers to those employees, we need this alert to be triggered.
