You should also create a ‘Anonymous’ (or whatever name you like) project userrole and assign that userrole to Anonymous users.
Then in your module create a role ‘Anonymous’ and make your employee information form visible for this role.
In your project security give the project Anonymous the module role anonymous. In your navigation set up a role based homepage and choose this page. Make sure to add a sign in button and sign in page for users if they do want to login.
