We do not recommend deleting employee files outside the House Cleaning process. Businesses are required to keep payroll records for a minimum period of 7 years, so we recommend you ensure that you are meeting legislative requirements for business record keeping before any employee files are deleted.
The House Cleaning process requires you to back up, so that you can always refer back to historical data from a prior period. Deleting employees in an ad-hoc way will make it very difficult to locate this type of historical information.
Note: If an employee was added by mistake or they didn't start with the Company, best practice is to restore the database back if they were added after your last PPE or enter their Termination date in their profile for the same date as their commencement date and this will free up the license.
