It's probably not productive to use poor analogies here.
Accessing a computer system without authorization from the owner of that system is a crime. Facebook doesn't give authorization for employers to access their employee's accounts on their system, and explicitly forbids their users from transferring their own authorization to others.
As far as I can see, there is simply no way to construe an employer's access as authorized by the owner of the system i.e. Facebook.
