No, removing a user from your workspace does not delete their hours.
You won’t be able to filter them out one-by-one, but the time they have tracked so far will remain accessible to you when you keep the user filter as ‘Everybody’ in the ‘Reports’ section. Here’s how you can get that user’s detailed tracking data:
Generate a Summary report, leaving the user filter empty (this will include everybody)
From the Group by the selection below the chart, choose Users
Click on the User’s name to go to a Detailed report of them with the previously selected filters.
If you still have questions about removing users, please contact our Support team by clicking on the purple chat icon in the bottom right corner of this page to start a chat or search through our knowledge base.
