1. Under the Employees tab at the top of your screen, click the blue Create Employee button.
2. Fill out the popup window, selecting all stores in which you would like your employee to be added. Once all employee information is filled out, press Submit in the bottom right corner.
Note - if you want an employee to access the Mission Control dashboard, the employee MUST be added to the headquarter location, as all Mission Control dashboard functionalities originate from the headquarter location.
