Hey Dan,
Thanks for writing in with a great question. Right now, we do not have a way to give an additional user a separate login to the account, though we are working on that for the future, but we don't have an eta for when this feature will be released. Currently, the only option to give another user access to the account is to share your login credentials with them, I'm afraid. In the meantime, if you would just like to share data with the employee, you can set up a custom reprot to be emailed directly to them from your campaign.
I apologize for the inconvenience while we work to add secondary logins to the account.
