How can an employer ensure that its employees are able to raise any concerns that they have about failures or wrongdoing within the organisation?

An employer should have a well-publicised whistleblowing policy and procedure to encourage workers to raise any concerns internally. The policy should encourage a culture of openness, and ensure that managers and workers are aware that victimisation for using the procedure will not be tolerated. It should indicate the sorts of matters regarded as relevant failures or wrongdoing, and include a clear statement that issues raised will be taken seriously and handled promptly. Workers should be able to raise concerns via a route other than the normal management structure. It would also be prudent for the employer to include the penalties for making false allegations maliciously, and the proper way in which concerns should be raised outside the organisation where necessary.
