Sage HR is an online payslips portal that you can log in to access your payslips and P60s online anytime. You can view them online and or download them.
When your payslips are uploaded you are notified by email that they are ready to view. However, this just provides a link for you to log in to Sage HR, it isn't the payslips itself.
If you'd rather be emailed your payslips directly, whether that is out of preference, you're having trouble logging in, or you don't have access to log in to Sage HR, then you must contact your employer or ex-employer directly about this. They can email a payslip or email a P60s to you if required.
Similarly, if you'd like your payslips printed and sent to you, this must be arranged by your employer.
