Employee seniority reporting varies from organization to organization. Some seniority reporting uses organization hire or start dates; special seniority dates; district service years; etc. to sort by.
If you use dates for your seniority reports, you will want to make sure the data is accurate before running any seniority reports. There are worksheets found in the Worksheets section of the Reporting menu that include the dates for easy review and updating. (Employee-Based IDS_Years_Dates and Job Base Setup)
If you use district service years for your seniority reports, there is a process that can be run to update the data in mass once a year in the Annual Employee Updates section of the Personnel menu. Click Increase Service Years for more information.
There are many seniority reports available in the General System Reports section of the Reporting menu. There are employee-based reports, job-based reports, and license-based reports. Many of these reports include a special Seniority Sort button at the top of the page to format the data in special formats.
