Your organization's Slack Enterprise Grid consists of dozens of workspaces with various access settings.

Ensure that the human resources team is adding the new employees to their respective workspaces. Set up and send a "Welcome to Slack" Slackbot message to all new employees introducing them to other public workspaces they can join.

Use identity provider (IdP) groups to assign new employees to their respective workspaces.

Ensure managers are adding their employees to their respective workspaces. New employees can browse other workspaces as they onboard and become more familiar with Slack.

Add new employees to user groups and assign the user groups to the respective workspaces.
