The plaintiffs evidentiary burden is merely to establish the factual basis for his claim that the retaliatory acts amounted to more than a de minimis injury. Accord Dawes v. Walker, 239 F.3d 489, 493 (2d Cir.2001) (<HOLDING>). Once this threshold has been passed, it is up

A: holding that the record contained insufficient evidence that increasing the prisoners work load would chill a prisoner of ordinary firmness from using the prison grievance process

D: holding that the defendant did not show prejudice to support ineffective assistance of counsel because any evidentiary error was harmless
C.
