When I go to the Admin () icon > Manage > People > agents, and view my list of agents, I see the words Support, Talk, or Chat next to their names.
Why are these labels showing next to their profiles?
As Zendesk expands to be a multi-product Support platform, it is necessary to identify which of your agents have access to each of the products on your Support account.
Since you have the ability to give agents access to some products, and not others, the labels next to your agents' profiles indicate the products enabled on their profiles.
For example, if you have an agent who only works with tickets and accepts phone calls (and Talk is enabled on their profile) then the "Support" and "Talk" labels will be indicated next to their name.
