A union representing service workers at UC Berkeley has filed a complaint with state authorities over the death of a custodian.

45-year-old Damon Frick died after falling from a lift on April 7 while washing window sills at a campus auditorium 20 feet above the ground.

The complaint filed with Cal OSHA says Frick never received proper safety training, and his supervisor assigned him the job even though those duties weren't part of his typical work.

Frick's family separately is pursuing a wrongful death claim against the university.
