Additional Resources

Several users have left your organization. You must modify the permissions of their files and directories to make them available to both their managers and the new employees taking over their tasks.

The following employees have left: Bill, Susan, and Juan.

Bill and Susan reported to Jason, and Juan reported to Sally. Bill was replaced by Nancy, Susan was replaced by Greg, and Juan was replaced by Jeremy.

The transfer of ownership should be as follows:

Bill --> Nancy and Jason
Susan --> Greg and Jason
Juan --> Jeremy and Sally

Use both user and group permissions to achieve this outcome.
