You have access to all the information on your coworkers in Cobot under Manage and then Members.
The text field above the list allows you to filter your coworkers by name, plan, status, etc. The Send Email to List link sends an email to all coworkers currently visible in the list. This allows you to send emails to specific groups of coworkers, e.g. all coworkers on a certain Membership plan.

This page allows you to change a coworker's plan, assign and track time passes, view attendance, view invoices, cancel their membership, etc. The panel in the upper-right corner gives you the space to add an Internal Memo to keep track of any special information on a coworker you might need to remember.
