How should I report?

Provide as much detail as possible, answering the questions what, when, where, why, who and how.

Inform us also if you have any concerns about retaliation.

You must report in good faith and to the best of your knowledge. If you deliberately provide false, incomplete or otherwise misleading information, you may be held responsible through disciplinary or other legal sanctions.

If possible, report in English, French or German.
