The icon for multiple profiles will change with the next release of Chrome. (A specific release date has not been announced, however the change could happen within the next several weeks.)
The icon, originally located at the top of the Chrome browser on the left hand side for Windows and the right hand side for OSX, will now display on the right hand side only. See a screenshot of the new icon below. Please keep in mind that you might need to re-login to Chrome once this update is implemented.
IT Administrators can install the Beta version of Chrome to see the new features before they are released. You can download the Chrome Beta at https://www.google.com/chrome/browser/beta.html.
