SIOUX CITY &#8212 Four former nurses have filed a lawsuit against Mercy Medical Center in Sioux City, claiming the hospital ignored their complaints that they were sexually harassed by a male nurse.

Colleen Barclay, Jennifer Cullenward, Judith Johnson and Glenda Pribil claim in the lawsuit filed Sept. 4 in federal court, that Adam Richter behaved in an “inappropriate sexual manner on a daily basis.”

Mercy Health Services, Mercy Health Network, Trinity Health Corporation and Trinity Health, Michigan, are named in the suit.

Mercy spokesman Mike Krysl said the hospital doesn’t tolerate sexual harassment and “plans to defend itself vigorously.”

The four nurses also claim they complained about Richter to management but were told they would have to “put up with it,” the lawsuit states.

Court documents show that Barclay, Cullenward and Johnson filed their complaints against the hospital first. Pribil, their supervisor, said she was demoted after the complaints and fired two months after she tried to address the situation.

Each of the nurses has either quit or been fired from the hospital this year, court records show.
