When dealing with blowing the whistle the first thing is to thinks if the disclosure of wrongdoing serve the public interest that meaning it impacts others, like the general public. Whistleblowers are safeguarded by law and should not face unjust treatment or job loss for coming forward. this is reinforced by the IET and the Government Whistleblowing for employees: What is a whistleblower – GOV.UK (www.gov.uk). If you Fail to raise a relevant concern it may cause a member liable to disciplinary action under our Rules of Conduct of the IET.
So if I Image that I discovered that the design is flawed and that there is a large probability that one or more of the first production cars will kill a pedestrian. Our team’s responsibilities as engineers having a problem we can’t fix alone would be to talk to our boss/supervisor . If that doesn’t work, we should use the company’s reporting system. Even if there’s no specific rule for whistleblowing, we should still try to tell someone at work. If the problem keeps going or if our boss/supervisor is part of it, they have to tell someone higher up, even outside the company if needed.
