If you are accessing LifeWorks on your mobile, via an app or a browser, you can press the menu icon in the top left of the screen. You will then see the notification icon (this looks like a bell) at the top of your screen, press this and it will take you to a list of all your notifications.
When you are logged into LifeWorks on a desktop, you can find the notification icon in the top right corner of the screen (next to your profile icon). When you click on this, it will drop down a short list of your notifications. You can press 'See All' at the bottom of this list, to view all your notifications.
