Although it is hard to imagine many cases where there would be an "official" action that would not clearly involve a tangible job action as presently defined, the court cites a 7th Circuit case as an example. There a transfer was deemed an "official" action under the circumstances, which made it justifiable to deprive the employer of the right to establish the affirmative defense. The bottom line is that for the most part employers will, to quote Justice Ginsberg, author of the majority opinion "be afforded the ... chance to establish through the Ellerth/Faragher defense that it should not be held vicariously liable," even in cases of constructive discharge.
As a side note, the Court endorses the general principles of constructive discharge:
"Did working conditions become so intolerable that a reasonable person in the employee's position would have felt compelled to resign" and that "[U]nless conditions are beyond 'ordinary' discrimination, a complaining employee is expected to remain on the job while seeking redress."
All in all a most sensible decision.
