The gist of a teacher’s FEHA claim for retaliation for filing a complaint with the DFEH was the defendant’s adverse employment action, not the protected activity of the investigation it conducted leading up to that action or its later protected action of defending the adverse employment action before a review commission. Accordingly, the case did not arise from conduct protected by CCP 425.16 and should not have been dismissed on a special Anti-SLAPP motion to strike.
