A Large Corporation Employs Nurses All Over the United States

A large corporation employs nurses all over the United States. Nurses in one agency learned that fellow nurses in another agency are striking because they are required to work 16-hour shifts to cover for nurses who have left due to unsafe staffing practices. The union of the nonstriking agency nurses decides to stop work to support the nurses who are striking; thus, this union:

A) is placing nurses at risk for a lawsuit because their direct employer did not cause the strike.
B) must be an industry union representing both parties.
C) is participating in a sympathy strike, which, if done correctly, is legal.
D) must pay for any losses incurred by the agency during the strike.
