This just in: Frank Turek is a noted Christian apologist and campus speaker who, I've just learned, also does secular team-building and training sessions for corporations. Read here from Mike Adams about how Turek was fired abruptly in the middle of a series for Cisco because someone googled his name during a session break and learned that he defends traditional marriage. The HR person who made the firing decision even thanked the googler for "outing" Turek.
Given the existence of religious anti-discrimination laws, I think Turek should seek legal counsel. It seems entirely plausible to my non-professional mind that he has legal recourse here.
