MINOT, N.D. — A federal agency is suing a North Dakota health-care provider for allegedly firing a pregnant employee instead of accommodating her pregnancy.

The U.S. Equal Employment Opportunity Commission filed a lawsuit Monday against Minot-based Trinity Health.

EEOC district Director Julianne Bowman says an investigation found that Trinity Health fired the employee once it learned of her pregnancy and her pregnancy-related disabilities. The agency alleges that when the woman requested light-duty work because of her restricted ability to lift, the health-care provider did not give her light-duty tasks available to employees injured on the job, and did not provide her with leave as required by law.

A Trinity Health spokeswoman says the health-care system does not comment on pending litigation.

Trinity Health operates in northwestern and central North Dakota and eastern Montana.
