Unless I am very much mistaken, here on planet earth in 2021 employers are required by law to have a variety of systems and policies in place to protect their employees, including, inter alia, whistleblowing and health and safety protocols.
In recent times, the scope and scale of personal liability of management and responsible persons has grown markedly, and as has been mentioned, can include prison.
Whilst I have no issue with the original poster airing the issues here, they might be better served by using the existing means at their disposal, which can mostly be invoked anonymously.
