To protect your online privacy, always fully sign out once you have finished using HR Self-Service. To do so, click on the arrow next to your name in the top right corner of your screen, and click 'log out'. The next screen will remind you that you are still logged in to the University of Oxford Single Sign-On system. This means there is a small risk that another person on that computer could access your account without first logging in. For complete security you should always close down your web browser (that includes quitting all running copies of your web browser) once you have finished working.
