When you re-employ a leaver in Sage 50cloud Payroll you must consider what email address the employee wants to use to access their future payslips. This is because they will have an email address already assigned to their old record from when they were previously employed by you.
If you re-add the returning employee in Sage 50cloud Payroll with the same email address as their old record, you are initially unable to upload payslips to Sage HR Online Services using this email address.
To reinstate the leaver you must either use a different email address or follow a process in Sage HR Online Services and Sage 50cloud Payroll to be able to use the same email address.
We run through these steps in our Sage 50cloud Payroll guide.
