The HR conversation
Hiring messages and employment contracts are delivered in a private one-to-one chat between the company and the candidate, called the HR conversation. It is separate from the company's customer conversations and from the team group.
The HR conversation carries the company's name, so the candidate is talking to the company. On the company side it is visible to the workspace's admins and HR managers; ordinary members cannot see it.
HR conversation and customer inbox
The customer inbox is where customers talk to your company. It is answered by the owner and the members allowed to handle customers. Keep employment matters (offers, contracts, salary) in the HR conversation, and orders and service questions in the customer conversation.
Both kinds of company conversation appear under the Business tab in Chats, apart from your personal chats.
To let someone handle recruitment without making them an admin, give them the workspace's HR permission. The hiring pipeline and HR conversations are available to owners, admins and members with HR permission.
