Go to settings/departments and select the department that you want everyone to be able to pull from and check the setting "Allow all agents to see the contents of this department." Doing this will allow your agents to see tickets in the queue for that department, even if they are not members of it. If you have this option unchecked, only members of the department can see its items in the queue.
