The simplest thing of all would be to have a single "User" model and a has_one sidecar model for the Client's extra fields. That way you can have just one set of login / logout paths and not worry about the logged-in person's underlying class. Using CanCan to manage the authorizations, you can allow an employee to see or do things that a client cannot, and vice-versa. Storing the "what kind of user this is" attribute in a column and switching permissions on that value is one of the simplest things to do in a multi-role application using CanCan. I recommend a quick read of the Wiki on that GitHub project.
