In action for wrongful termination and age and disability discrimination, summary judgment for defendant is affirmed where: 1) Government Code section 815.2(b) provides immunity to a public entity for its vicarious liability for the wrongs of its employees and its own direct liability; 2) the trial court correctly found that plaintiff failed to make a prima facie showing of age discrimination; and 3) plaintiff's notation on his FEHA complaint that he was "36.5% disabled" did not create a triable issue over whether he exhausted administrative remedies.
