To me, ethics in my professional life is no difference from the law in my daily life. If you break the law, then you will be put into jail; similarly, if you don't follow ethics, then you jeopardize your professional career.
Every year, there are compulsory ethics trainings that you need to attend and pass exams.
At last, Google now has trashed its ethics trying to impress the stock market. Now, Google is the new evil.
