The Michigan Nurses Association filed a complaint against Traverse City, Mich.-based Munson Medical Center with the National Labor Relations Board, the hospital confirmed Friday.
The complaint, which comes as some nurses have tried to unionize, alleges the hospital violated the National Labor Relations Act "by interrogating employees, tampering with schedules and giving false information about unions," according to WPBN-TV.
"We've just been concerned for a long time that we aren't respected as much as we should be," Cindy Rydahl, a registered nurse at Munson Medical Center, told the TV station.
The hospital denies the allegations, saying in an emailed statement it "hold[s] our nurses and the nursing profession in the highest regard," and respects the employees' right to form a union.
"During this process, we have provided our nurses accurate information to help them make an informed decision about union membership. We strongly believe that we can deliver the best care for patients and their families by working in harmony with our nurses, without a third party standing between us," hospital officials added.
Munson Medical Center said it has not seen specific details "to substantiate the vague allegations in the complaint." However, the hospital said it will examine the details closely if they are presented to the NLRB.
"We are confident that we have acted within the law. Munson Medical Center has made great efforts to train our supervisors on the appropriate ways to interact with our employees regarding union organizing efforts. We will continue to follow the law," the hospital added.
Meanwhile, nurses are trying to collect signatures to gauge support for unionization, and will seek an election if enough support is there, according to the report.
