Users are not notified when a timeline post is created in a Workspace or Page. However, the element appears in their global timeline.
Only when you react to a post, i.e. you comment or leave a like, then you subscribe to the post and receive notifications about the actions of other users (e.g. new comments of other users). If you are the author, you will receive notifications about new comments in the discussion section and when you are mentioned.
"Sticky posts" are an exception: If a sticky post is written on a page you follow, it is obligatory for everyone at the top of the (global) timeline and must be deliberately marked as "read".
