When you invite a new user, you can choose between two different access tiers:
Admin - Can view and manage all of the settings for the company, this includes:
Setting up the Org Chart
Managing Connections
Setting Departments
Team Member - Only has access to their direct reports information - this is usually the role for people managers
Slack Only - If you only want to grant Windmill access to managers, your individual contributors can still interact with Windmill as Slack Only users. This means they will receive feedback requests, edit their accomplishments, but will not have access to gowindmill.com or their profiles. For Slack Only users, they will not need invites to access the Windmill platform.
If you ever need to change a user's permissions, you can do so in Settings, under the "Employees" tab.
