If you are an admin you can simply remove a user by navigating to users and selecting the user you would like to remove.
To remove a user
- Navigate to the users - click on them in the list
- In the right corner you will see options which will enable you to deactivate a user.
Once a user has been deactivated they won't receive an onboarding, offboarding or survey. Please note that this is permeant action and can't be undone.
