In the whistleblower system, you can report serious matters such as, e.g., bribery, theft, fraud, breach of insider rules, breach of competition law and violations of human rights and labor standards (e.g. harassment and discrimination), etc.
In some countries, there are specific restrictions on what and how you can report. You will receive the relevant instructions on the reporting page.
Matters such as bullying, dissatisfaction with wages, violations of the alcohol policy, etc., should not be reported here. They should instead be reported through the normal channels.
