Managers (and Employees if you allow them on your
SETTINGS>Global Employee Permissions page) can get a quick view of who is
scheduled to be working right now or scheduled later
today using the ON NOW section.

Click the "Show Those Working Later Today" or the "Show all of Today's
Shifts" links to see those lists.
On your
SETTINGS>Employee Permissions page you can also
allow employees to see this view when they sign in.
