i think you are not right. I fully agree with one of comments earlier that whistleblowers rights are for company's breaking the law, not for in house bad software systems

I am an employer, and from my side, the dismissal of an employee is a common thing, but only if he systematically violates discipline. I do not know how this happens in your company, but if you didn’t have any complaints or gross violations, I don’t understand your management at all. Almost all the years of our company, we use software to monitor the actions of employees , and we are always sure if our staff is guilty or not. I can advise you to find like-minded people and write a collective complaint, perhaps the management will take it into account
