Rolls-Royce set up the 'ethics line' as a response to several allegations of bribery within the organisation.
In December, the Serious Fraud Office launched an investigation into Rolls-Royce and concerns about bribery and corruption in overseas markets. This week, the Indian Central Bureau of Investigation launched a separate probe into the jet engine manufacturer.
Unite has 413 members in the company's Derby headquarters. Regional officer Tony Tinley told HR magazine the initiative must be implemented in the right way to succeed.
"We’ve come across this approach before from US companies. It is important that it is not a gimmick and addresses the issues raised," he said.
Tinley said a more grassroots approach might be more effective in dealing with these problems.
“Unite would prefer that the grievance procedure is used to ensure that stringent standards of complaint handling are adhered to," he said. "We would also say to Rolls-Royce that there is no substitute for training managers on acceptable conduct."
Tinley believes the issues at Rolls-Royce will not be resolved until the management culture within the organisation changes.
“We question whether the problems Rolls-Royce face will ever truly be dealt with while the company’s bonus culture places the emphasis on cash rewards for managers rather than quality outcomes for the business," he said.
In a press statement, Rolls-Royce chief executive John Rishton insisted the company is taking a hardline approach to any wrongdoing by employees.
"I want to make it crystal clear that neither I, nor the board, will tolerate improper business conduct of any sort and will take all necessary action to ensure compliance," he said.
Rolls-Royce declined to comment further on their whistleblower hotline when contacted by HR magazine.
