All you need to do is click on Manager! On your manager dashboard, you'll see a section labelled Upcoming Courses By. In this section, just use the drop-down menu to choose between Deadline and Expiration dates.
In each section, you'll see a list of courses you oversee that have users with either a deadline or re-enrollment coming up within the next two weeks, depending on the option you choose. Clicking on an entry will bring up a list of the users that have something upcoming. From here, depending on your permissions, you'll be able to download reports, check/edit their course progress, and look at their overall progress in their courses.
