ZEELAND, Mich. (AP) - A health care center in western Michigan is accused of agreeing to requests by patients for white-only caregivers. Six black certified nursing assistants filed a lawsuit April 11 against Providence Healthcare and Rehabilitation Center, where they all work or formerly worked. The Zeeland facility offers memory care, rehabilitation, retirement and assisted living to mostly senior patients. The CNAs are accusing the center of race discrimination, race harassment and retaliation. They're seeking compensation for mental anguish, emotional distress and damage to their professional reputation. Providence Life Services spokeswoman Sheila King declined to comment on the allegations due to the litigation but said Providence doesn't change staff assignments based on race. The center falls under a nonprofit that also has locations in Illinois and Indiana.
