Two separate investigations are looking into reports of patient and staff abuse at the Kalamazoo Psychiatric Hospital.
The state-run hospital has been embroiled in controversy since a patient died from a lack of oxygen in March.
Meanwhile, staff at the hospital are being repeatedly injured by violent patients, says AFSCME's Stacie Dineen.
"I'm talking serious injuries, where they get their eye gouged or they get concussions or they have the stuffing beat out of them."
