Disagreements with button proximity

On the Sign In page, we have two links. One is for Clients, which is the primary login form. There is a button for our Employee Login, which is a Single Sign On process.

I put the button on the top right initially to separate those experiences.

Product Management wants me to put it on the bottom of the login page, because they think it will confuse the users at the top right. However, referencing the Gestalt Principle - I believe by placing the Employee Login Button in closer proximity to the login form will actually create more confusion.

Ideally I would like to A/B test this, but currently, we haven't recruited any users willing to participate in the user testing. (I'm a one-man show, so it's incredibly overwhelming. Any suggestions on how to user test online would be very appreciated!)

Based on your experience and knowledge, which option makes more sense? (Pictures included below.)
