If you are going to play ethics games, you should probably make sure you have a credible compliance program. If you talk about doing the right thing but don't enforce it, employees can become bitter. If management preaches ethical behavior but ignores problems, the people playing the ethics games may think it is a dishonest experience. If there are investigations, auditing, monitoring, discipline and reporting to the Board, then the games may help. If all you do is write a code of conduct and produce a video with the CEO telling everyone, "We are an ethical company," the ethics games could frustrate some people. They will think the effort lacks integrity. I see many organizations that put a majority of their time into these kinds of efforts and very little time into compliance. Employees who do not see an effort to root out problems and punish unethical behavior may not want to play these games.
