Slack admins can now designate any channel to be used for announcements only, a move aimed at minimizing distractions and ensuring that important information is communicated to workers.
While it’s already possible to limit posting in the default #general channel in Slack workspaces, the change unveiled today allows admins on Slack’s paid Plus and Enterprise Grid plans to restrict other channels as well. So, for instance, #it-announcements or #emea-announcements channels can be restricted to broadcasting information only.
The goal is to prevent employees from posting messages in channels intended for announcements (such as IT-related requests in an IT announcements channel), which can lead to other workers muting the channel and ignoring it completely.
